Use the sum and difference identities to determine the exact value of the following expression.sin(2π3−π4)
Question
Solution 1
Sure, let's use the sum and difference identities to solve the expression sin(2π/3 - π/4).
The difference identity for sine is: sin(a - b) = sin(a)cos(b) - cos(a)sin(b)
Let's plug in our values into this formula:
sin(2π/3 - π/4) = sin(2π/3)cos(π/4) - cos(2π/3)sin(π/4)
We know that sin(2π/3) = √3 Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
