Question

cos 48 -sin 42=________​

Answer 1

Answer:

Valueof cos48degree-sin42degree=0

Step-by-step explanation:

Value of cos48degree-sin42degree

=cos48degree-sin(90-48degree)

=cos48degree-cos48degree

* We know that,

Sin(90°-A)=cosA *

=0

Therefore,

Value of cos48degree-sin42degree=0

Answer 2

Hey friend,

Here is the solution :-

$\cos(48) - \sin(42) \\ \\ \cos(90 - 42) - \sin(42) \\ \\ \sin(42) - \sin(42) = 0$
