Evaluate tan 330

Question

Tan represent s or mean tangent

Answer 1

Tan 330 has a reference angle of 30. The tan 30 = √3/3

The only difference is the sign for Tan 330. 330 is in Quadrant 4, so the signs are (+, -)

Tan = y/x so the signs would be -/+ or -

so Tan 330 = -√3/3

You just need to memorize the sin/cos/tan for 30/45/ 60/90 and you can find any trig function in any quadrant.

Hope this helped : )
