Question

(1) sin (A + B) = sin A + sin B.
(mm) The value of cos o increases as o increases.
(iv) sin 0 = cos e for all values of 0.
(v) cot A is not defined for A = 0º.
State whether the following are true or false. Justify your answer.
(i) The value of sin 0 increases as O increases.​

Answer 1

Answer:

i) False, sin (A + B) = sin ACosB + CosAsin B.

iv) False, sinA is not equal to cosA for all values of A.

v) true, cot A is not defined for A = 0º.

note

The value of sinθ

increases as θ increases is not correct for all θ

so, This statement is False
