If sin^2Θ - cos^2Θ = 0, prove that: sinΘ = 1/√2
Answer:


This question is pretty simple to solve. We need to first see which value is needed? It's cos or sin? If it is sin then change the cos into sin and if the value is asking for cos then change the sin into cos. As shown in the above figure, we use the identity,

Cos²x = 1- sin²x

And we perform the basic Mathematics and prove that the value of sin 'theta' is equal to
 1/√2.

So, this is how you prove the Trigonometric value of, . If sin^2Θ - cos^2Θ = 0, prove that: sinΘ = 1/√2, in Trigonometry of Mathematics.
