Question

If sin a = 1 then the value of cos a is

Answer 1

Answer:

gievn

sin a = 1

=> sin a = sin90°

=> a = 90°

now.

cos a

= cos 90° = 0

so, the value of cosA = 0.

Answer 2

Answer:

$given \: that$

$\sin(a) = 1$

$\sin(a) = \sin(90 \degree )$

$(a) = 90\degree$

$then$

$\cos(a)$

$\cos(90\degree) = 0$

$\cos(a) = 0$

$so\:the\:value\:of\:cos (a)=0$
