Chapter 7: Q. 7 (page 485)

True or False $\sin (α + β) = \sin α + \sin β + 2 \sin α \sin β$

Short Answer

Expert verified

$\sin (α + β) = \sin α + \sin β + 2 \sin α \sin β$ is false.

Step by step solution

Step 1. Given information

Given that $\sin (α + β) = \sin α + \sin β + 2 \sin α \sin β$ .

We have to tell whether this is true or false.

Step 2. Write the sum of sine function formula

The sum of sine function formula is $\sin (α + β) = \sin α \cos β + \sin β \cos α$ .

Therefore, the given equation is false.
