Signs of the Trig Functions by Quadrant Worksheet with Answer Key

What's on the worksheet

1. Name the quadrant of θ.
   \tan\theta > 0 and \csc\theta < 0\sin\theta > 0 and \sec\theta < 0\csc\theta > 0 and \sec\theta > 0\csc\theta < 0 and \cos\theta > 0\sec\theta < 0 and \tan\theta < 0
2. Decide whether each value is positive or negative, without a calculator.
   \cos 172^\circ\tan 218^\circ\csc(-200^\circ)\cot\dfrac{7\pi}{5}\sec\dfrac{5\pi}{9}
4. An angle θ has θ = 6111.
5. Decide the sign of each expression without a calculator.
6. For θ in a quadrant (not on an axis), find the quadrants in which each statement is true.
