Question

if sin A = 1 than what is the value of COS A ?​

Answer 1

sinA=1

also sin90°=1

so A=90

so cos 90°=0

Answer 2

Answer:

given, sin A =1

we know that

sin A = p/h

1/1 =p/h

now by Pythagoras theorm,

h^2 = p^2 + b^2

(1)^2 =( 1)^2 + (b)^2

1 = 1 + b^2

1-1 =b ^2

0 = b^2

so , b =√0

=0

now ,

cos A = b/h

= 0/1

=0

so cos A =0.

hope this helps you ❣️❣️...
