4. Sketch the standard position angle C = cos-1 (-1/4)

Question

Question

4. Sketch the standard position angle C = cos^-1 (-1/4)

(Be sure to label the angle C and show how the quantities - 1 and 4 are related to the angle.)

5. Use your sketch of the previous problem to find the exact value of tan C.

(exact value will be a fraction involving a square root; it is not a decimal approximation)

Answer 1

Answer #1

tanC=-√15 or (-√15/1).
