Therefore, the value of trigonometric functions are: Sin x = 12/13, cos x = -5/13, tanx = -12/5, cosex x = 13/12, sec x = -13/5. Get Textbook solutions for maths from evidyarthi.in Considering the unit circle, the six important trigonometric functions are given as follows: The other trigonometric functions in terms of sine and cosine functions are given as follows: Some of the important expressions for the trigonometric functions of the sum and difference of two angles and related expressions are given as follows: Go through the below given trigonometric functions class 11 solved problems: Convert 6 radians into the degree measure. As we know that the circle subtends at the centre of an angle whose radian measures 2π, and its degree measures 360 degrees. An angle is a measure, which gives the rotation of a ray about its initial position. By using the trigonometric identity, the above expression is written as: Now, cross multiply above expression, we get, Tan 3x – tan 3x tan 2x tan x = tan 2x + tan x. tan 3x tan 2x tan x = tan 3x – tan 2x – tan x.
