Question

Evaluate the following expression: cos((cos^-1(4)/7)-((sin^-1(2))/12)) Give an exact answer

Answer 1

No trig functions allowed.

Answer 2

Well,

\(\cos^{-1}\left\{\cos(\theta)\right\}=\theta \)

Answer 3

I meant
\(\cos\left\{\cos^{-1}(\theta)\right\}=\theta\)

Answer 4

\(\cos\left\{\dfrac{\cos^{-1}(4)}{7}-\dfrac{\cos^{-1}(2)}{12}\right\} \)

this?

Answer 5

oh the second one is sin^-1

Answer 6

\(\cos\left\{\dfrac{\cos^{-1}(4)}{7}-\dfrac{\sin^{-1}(2)}{12}\right\} \)

Answer 7

Yeah

Answer 8

I will do an example

Answer 9

ok

Answer 10

I had to leave, apolgoize

Answer 11
