Question

What is the value of (tan A - sin A) /sin 3A

Answer 1

Answer:

The value is =- 0.7735

Step-by-step explanation:

Such types of questions can be solved easily and we can get the numerical value of those if we substitute a value for A

In this case I am substituting A = 30

Value of sin A= sin 30 =1÷2

Value of tan A= tan 30 =1÷√3

Value of sin 3A = sin 90 = 1

(tan A - sin A) /sin 3A = (0.5- 0.57735) = -0.7735
