WebIn mathematics, the trigonometric functions are a set of functions which relate angles to the sides of a right triangle.There are many trigonometric functions, the 3 most common being sine, cosine, tangent, followed by cotangent, secant and cosecant. The last three are called reciprocal trigonometric functions, because they act as the reciprocals of other functions.

WebNov 20, 2024 · 2 Answers. I figured out how to solve this. π / 2 < θ < π means that we are working in the second quadrant, so we can set θ = 2 π 3 and plug θ into the statement given which is cos ( θ 2). If we do that, we get cos ( π 3), which is equal to 1 2, and 1 2 > 0. Therefore, the statement, if π 2 < θ < π, then cos ( θ 2) < 0, is false. shunvav.comWebJun 30, 2024 · How do you find the values of the six trigonometric functions given cot θ is undefined and π 2 ≤ θ ≤ 3π 2?
