How do you solve 2sin^2θ = 1 ?
Murrr4er [49]

The value of θ is 45 degrees as sin45° is equal to 1/√2.

<h3>What is trigonometric equation?</h3>

Trigonometric equation refers to an equation consists of a number of trigonometric ratios whose angle is unknown.

<h3>What is the ranges of trigonometric angle?</h3>

Generally trigonometric angles are represented by θ. while solving equations we get the values of θ ranges from 0 degree to 90 degrees.

Given, 2sin²θ = 1

solving the equation

      sin²θ = 1/2

     sinθ = 1/√2

we know sin45° has a specific value 1/√2

   sinθ = sin 45°

now, θ = 45°

hence, the solution is θ = 45 degrees.
