#1

find all solutions of the equation in the interval [0,2pie). In cases

where a calculator is necessary, round the answers to two decimal

places.

sin(sinx)=pie/6

#2

A 100 ft vertical antenna is on the roof of a building. From a point on

the ground, the angles of elevation to the top and the bottom of the

antenna are 51 degrees and 37 degrees, respectively. Find the height of

the building.

#3

the length of the three sides of a triangle are denoted a, b, and c;

the angles opposite these sides are A,B, and C, respectively. In each

exercise, use the given information to find the required quantities.

c=4, a=2, B=90 degrees

find sin^2(A) + cos^2(B)
