Write each of the following as a function of theta.
1.) sin(pi/4 - theta) 2.) tan(theta+30°)

Step-by-step explanation:

Let x represent theta.

Using the angle addition trig formula,

Multiply one side at a time

Replace theta with x , the answer is

2. Convert 30 degrees into radian

Using tangent formula,

Tan if pi/6 is sqr root of 3/3

Since my phone about to die if you later simplify that,

you'll get

Replace theta with X.
