Answer:
Step-by-step explanation:
We want to verify the identity:
Let us take the LHS and simplify to get the LHS.
Express everything in terms of the cosine and sine function.
Collect LCM
We simplify the RHS to get:
We rationalize to get:
We expand to get:
Factor negative one in the denominator:
Apply the Pythagoras Property to get:
Simplify to get:
Or
Divide both the numerator and denominator by sin x
This finally gives:
The answer is “the initial deposit is $200” and “the annual interest rate is 1.5%”
