In the following problems the values of sin()sin() and cos()cos() are given. Determine the value of tan()tan().

a. sin()=0.644sin()=0.644 and cos()=0.765

tan ()= ?

b. sin()=0.058sin()=-0.058 and cos()=0.998cos()=-0.998

tan ()= ?

c. sin()=0.926sin()=-0.926 and cos()=0.378

tan ()= ?

Solution

a) tan() = sin()/cos() = 0.644/0.765 = 0.84183

b) tan() = sin()/cos() = -0.058/(-0.998) = 0.058116232

c) tan() = sin()/cos() = -0.926/0.378 = -2.449735
