Question

raju said the value of sin90°, cos0°, tan45° are in AP? justify​

Answer 1

Answer:

Yes, the value of sin 90°, cos 0°and tan 45°are in AP.

sin 90°=1

cos 0°=1

tan 45°=1

therefore, sin 90°, cos 0°, tan 45°

=1, 1, 1

so, a=1, d=a2-a1=1-1=0

a3-a2=1-1=0

so common difference=0

First term=1

So, it is in A. P.
