Compute the following and leave your answers in exact form. (A.) arccos(sin(60degree)) (B.) tan(arcsin(2/2)) (C.) sin(arcsin(0.34)) (D.) arcsin(sin(120degree)) (E.) arccos(cos(-63degree)) Find theta below. Round your answer to two decimal places. Find theta below. Round your answer to two decimal places.

Solution

1)a) arccos(sin60⁰)

= arccos(cos(90-60)⁰)

= arccos(cos(30)⁰)

=30⁰

b)tan(arcsin(2 /2))

let arcsin(2 /2)=p

=>sinp =2 /2

=>tanp =2 /2

=>tanp =1

tan(arcsin(2 /2))

=tan(arctan(1))

=1

c) sin(arcsin0.34)

=0.34

d)arcsin(sin120⁰)

=120⁰

e)arccos(cos(-63))

=arccos(cos(63))

=63⁰

2)tan =5/2

=> =arctan(5/2)

=> =68.20⁰

3)cos=6/10

=arccos(6/10)=53.13⁰
