Question

What are the sine, cosine, and tangent of Θ = 3 pi over 4 radians?

Answer 1

StSin 135° = 0.7071

Cos 135° = - 0.7071.

Tan 135 = 1

Explanation:

We are given that;

θ = 3π/4 rads

Now, 3π/4 in radius means that θ = 135°

Thus;

Sin 135° = 0.7071

Cos 135° = - 0.7071.

Tan 135 = sin 135/cos 134 = 1
