It's not. The tangent of 180 degrees is zero.
Consider tan(x) = sin(x)/cos(x). When x = 180 degrees, sin(x) = 0 and cos(x) = -1 and so tan(x) = 0
The tangent of 90 degrees is undefined. This is because the tangent function is defined as the ratio of the sine to the cosine, and at 90 degrees, the cosine is zero, leading to division by zero. Therefore, the tangent approaches infinity as the angle approaches 90 degrees.
180 degrees, or pi.
pi radians (180 degrees).
Zero and any other multiple of 180 degrees.
The tangent function is a periodic function with period 180 degrees sotan(360) = tan(360-2*180) = tan(0) = 0.
The tangent of 90 degrees is undefined. This is because the tangent function is defined as the ratio of the sine to the cosine, and at 90 degrees, the cosine is zero, leading to division by zero. Therefore, the tangent approaches infinity as the angle approaches 90 degrees.
Although you learn the trig. functions between 0 - 90 , they are a continuous 'wave'; from negative infinity to positive infinity. So you can put in any degrees value into a Sin/Cos function, and the answer will always be between '-1 & 1'. e/.g/ Sin ( 1080 ) = 0 Cosine ( 1080 ) = 1. So for 180 degrees. the sine function rises from 0 to 90 and then fall back from 90 - 180 Sine(180) = 0 . Cos (180) = -1 Tan(180) = 0 Csc180) = 1/ Sin = 1/0 ( undefined) Sec( 180) = 1/Cos = 1/-1 = -1 Cot( 180) = Cos/Sin = 1/0 ( undefined(.
180 degrees, or pi.
pi radians (180 degrees).
60 * pi / 180
Because it tends to infinity. Additionally, tangent can be expressed as sin theta divided by cos theta. The sine of 90 is 1. The cosine of 90 is 0. That would be 1 divided by 0, or division by zero; which is undefined.
Zero and any other multiple of 180 degrees.
The tangent function is a periodic function with period 180 degrees sotan(360) = tan(360-2*180) = tan(0) = 0.
Every multiple of 180 degrees, beginning with zero.
All positive and negative multiples of 180 degrees. (pi radians)
-pi/2 and pi/2
It is k*pi radians or k*180 degrees for integer k
