Question

if sin threa = a, then find cot threa


please say the solution and ​

Answer 1

Answer:

cot Ф =1/a√ (1-a²)

Step-by-step explanation:

sin Ф = a

so cosec Ф= 1/a

cot² Ф= cosec²Ф-1

=1/a²-1

cot² Ф=(1-a²)/a²

so  cot Ф =1/a√ (1-a²)

Answer 2

Answer:

Here, Sin theta=a

it's mean, Cos theta=√1-Sin² theta

=√1-a²

So, Cot theta=Cos theta/Sin theta

= √1-a²/a
