Learn how to determine the quadrant of an angle given in radians. Recall that 1 radian is the distance on the circumference of the circle that is equivalent to the radius of the circle. Also recall that the circumference of a circle is equivalent to 2pi radians. To determine the quadrant of the angle in radians written in terms of pi, we divide the top half and the bottom half of circumference of the circle into the number of parts corresponding to the denominator of the radian angle. Then we count from the positive x-axis in an anti-clockwise direction for positive angles and in the clockwise direction for negative angles the number of parts corresponding to the coefficient of pi in the numerator. The quadrant where the number of parts corresponds to the coefficient of the pi in the numerator of radian angle is the required quadrant.

Learn how to sketch angles in terms of pi. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360 degrees. Angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction. We measure angles starting from the positive x-axis. To sketch an angle in terms of pi, we make use of the knowledge that the angle made by a circle is 2pi and that made by a straight line is pi. So, we first sketch a circle which we will divide into two. Next we divide each half of the circle into the number of parts corresponding to the denominator of the angle we want to sketch. The number of parts corresponding to the numerator of the angle we are sketching from the 0 radians point is the angle we are looking for. #trigonometry #sketchangles #trigonometry #anglesintrigonometry

Learn how to evaluate the six trigonometric functions given some constraints. When given the value of one trigonometric function, we can use a right triangle with one of its legs on the x-axis and the other leg, perpendicular to the x-axis is drawn such that the reference angle is at the origin. The x-coordinate of the given point represents the adjacent of the reference angle while the y-coordinate represent the opposite of the reference angle. The hypothenuse is the line joining from the origin to the terminal side of the 'opposite' line. Using the Pythagoras theorem, we can obtain any of the unknown sides of the right triangle. Having the opposite, the adjacent and the hypothenuse of the reference angle of the right triangle, we can then evaluate the other trigonometric functions accordingly within the given constraint. #trigonometry #evaluatetrigonometricfunctions

Learn how to determine the quadrant of an angle given in degrees. Recall that the circumference of a circle is equivalent to 360 degrees. Also recall that each quadrant is equivalent to 90 degrees. To determine the quadrant of the angle given in degrees, we determine the number of 90 degrees in the given angle. The quadrant where the remainder of the given angle that is not up to the next multiple of 90 lies corresponds to the quadrant of the given angle. For angles greater than 360 degrees, we first make the number of 360 degree turns in the given triangle before determining the number of 90 degrees in the remainder that is not up to the next multiple of 360 degrees. Note that the direction is in an anti-clockwise direction for positive angles and in the clockwise direction for negative angles from the positive x-axis.

Learn how to determine the quadrant given the constraint. The plane is divided into four equal parts called the quadrants with the region between the positive x-axis and the positive y-axis called the 1st quadrant having angles 0 to 90 degrees, the region between the negative x-axis and the positive y-axis called the 2nd quadrant having angles 90 to 180 degrees, the region between the negative x-axis and the negative y-axis called the 3rd quadrant having angles 180 to 270 degrees and the region between the positive x-axis and the negative y-axis called the 4th quadrant having angles 270 to 360 degrees. The value of the six trigonometric functions is either positive or nedgative depending on the trigonometric function and the quadrant in which the angle lies. While all the six trigonometric functions are positive in the 1st quadrant, only sine and cosecant are positive in the 2nd quadrant, tangent and cotangent are positive in the 3rd quadrant and cosine and secant are positive in the 4th quadrant. Thus, given the constraints on the value(s) of the trigonometric functions, we can find the quadrant of the angle accordingly. #trigonometry #evaluatetrigonometricfunctions

Learn the basics of co-terminal angles. An angle is a figure formed by two rays which have a common endpoint. The two rays are called the sides of the angle while the common endpoint is called the vertex of the angle. We measure angles starting from the positive x-axis, i.e. the initial side of an angle measure is usually the positive x-axis. Angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction. Two or more angles are said to be co-terminal when they have the same initial and terminal sides. Coterminal angles are found by adding/subtracting 360 degrees (for degree angle measure) or 2pi (for radian angle measure) to/from the given angle. #trigonometry #anglesintrigonometry

Next we divide the circle in such a way that the third division is just abov the halfway point of the circle. and the 6th division is just before one revolution about the center of the circle. The number of parts corresponding to the angle we are sketching from the 0 radians point is the angle we are looking for. #trigonometry #sketchangles #trigonometry #anglesintrigonometry
