Find the exact value of the expression using the provided information.

Find tan(s + t) given that sin s =1/4 , with s in quadrant II, and sin t=-1/2 with t in quadrant IV

Step 1

sin s= 1/4 = opposite / hypotenuse. Let opposite=1 and hypotenuse = 4. Adjacent = x

s is in quadrant 2. There x is negative.

x=-sqrt(15)

Step 2

tan s= -1/sqrt(15)

Step 3

sin t= - 1/2 = opposite / hypotenuse. Let opposite= - 1 and hypotenuse = 2. Adj...
