Question

If sin square a = 2 sin a then find the value of a.

Answer 1

Answer:

0

Step-by-step explanation:

sin²a = 2 sin a

sin²a- 2sina = 0

taking common out,

sin a(sina -2)=0

sina=0 or sin a = 2

but since sin cannot have a value higher than one

sin a = 0

thus a = 0

Answer 2

Answer:

Step-by-step explanation:

Given,

Sin²A = 2 SinA

=>Sin²A/SinA = 2

=>SinA=2

Now take the value of A in degrees...
