Question

If 1- cos square theata =1/4 then sin theata = .
please answer the question.​

Answer 1

Answer:

+1/2 , - 1/2

Step-by-step explanation:

• sin^2( theta) + cos^2 (theta)= 1
• 1 - cos^2 ( theta) = sin^2 (theta)
• According to question this value is = 1/4
• this implies sin^2(THETA)= 1/4
• sin(theta)= $\sqrt{1/4}$= +1/2 or - 1/2
