Question

If sec A ,.sin A =0, then find the value of A

Answer 1

Answer:

sinA becomes 0 only when A=0

Answer 2

Answer:

A = 0°

Step-by-step explanation:

Given that

secA.sinA = 0

=> secA.sinA =0

=> sinA/cosA = 0 (since secA = 1/cosA )

=> tanA = 0 (since sinA/cosA = tanA )

=> tanA = tanO° (since tan0° = 0 )

=> A=0°

Therefore, value of A = 0°
