Chapter 7: Q. 70 (page 496)

In Problems 69-78, solve each equation on the interval 0鈮�胃<2蟺.

cos2胃=2-2sin2胃.

Short Answer

Expert verified

The equation cos2胃=2-2sin2胃has no solution (i.e), 胃鈭�蠒.

Step by step solution

01

Step 1 Given equation is,

cos2胃=2-2sin2胃.

we know that, cos2胃=1-2sin2胃

Substitute the known values in the given equation.

1-2sin2胃=2-2sin2胃1鈮�2

02

Step 2 The above equation indicates that the given equation has no solution.

So, the solution set is, 胃鈭�{蠒}.
