Question

HOLA,




$\huge \fbox \red{❥ Question}$




If 3 cot A = 4, check whether (1 – tan2A)/(1 + tan2A) = cos2 A – sin2 A or not.​

Answer 1

Answer:

yes,LHS=RHS

Step-by-step explanation:

If 3 cot A = 4,

LHS

If tan A= 3/4

then sin A=3/5 (from trigonometric functions)

cos A= 4/5

So,apply these values in RHS

Hence RHS= LHS

yes,for the given value both LHS =RHS
