Question

sin A=12/13 find other trignometric ratios of angle A
​

Answer 1

Answer:

sin A = 12/13

cos A = √( 1 - 144/169)

=√( 25/169

= 5/13

tan A = sin A / cos A

= 12/5

cot A = 1/ tan A

=5/12

sec A = 1/ cos A

= 13/5

cosec A = 1/ sin A

=13/12

I can't include the signs cause it isn't clear from the question in which quadrent it lies.

Hope you will confirm it
