Question

3. If thita = 45°,then find the values of 2 sinthitacosthita. ​

Answer 1

Answer:

thita= 45 degree

2×sin45degree×cos45degree

2×1/√2×1/√2

2×1/2

=1 ans

Answer 2

Answer:

Answer is 1.

Step-by-step explanation:

Given,

∅ = 45°

2sin∅.cos∅

= 2sin45°.cos45°

= 2(1/√2)(1/√2)

= 2(1/2). (Since denominator is √2.√2 = 2)

= 2/2

= 1

:. 2sin∅.cos∅ = 1.
