Question

Evaluate tan(sin^-1(-4/5)). Enter your answer as a fraction using the slash bar (/).

Answer 1

-4/3

Explanation:

assuming the S is capital in Sin^-1 (4/5)

Answer 2

-1333/1000

Explanation:

Evaluate tan(sin^-1(-4/5)).

First we need to evaluate the expression in parenthesis

sin^-1(-4/5)

= sin^-1(-0.8)

= -53.13

SUbstitute the given value into the original expression as shown;

tan(sin^-1(-4/5))

= tan(-53.13)

= -1.333

= -1333/1000

Hence the required answer is -1333/1000
