Question

If y=sin 2 theta then find ' theta ' where will be maximum.​

Answer 1

y will be maximum at Ф = 45°.

Given:

sin2Ф

To Find:

Theta 'Ф' where y will be maximum.

Solution:

We know that,

Sine function will be maximum at 1.

Hence,

y = sin2Ф = 1

At 90°, the value of sine function is 1.

So,

2Ф = 90°

=> Ф = 90°/2

=> Ф = 45°

Hence, y will be maximum at Ф = 45°.
