text: 1 − sin 2 ⁡ ( θ ) sin ⁡ ( θ )
text: cos 2 ⁡ ( θ ) + sin 2 ⁡ ( θ ) = 1 {\displaystyle \cos ^{2}(\theta )
text: sin 2 ⁡ ( θ )
text: The graph of ( sin ⁡ ( x ) ) 2 {\displaystyle (\sin(x))^{2}} , or sin 2 ⁡ ( x ) {\displaystyle \sin ^{2}(x)} as it is more usually written, is shown below:
text: We will show this is true later when we look at double angle formulae and prove that sin 2 ⁡ ( x )
text: that: cos 2 ⁡ ( x ) + sin 2 ⁡ ( x ) = 1 {\displaystyle \cos ^{2}(x)+\sin ^{2}(x)=1} and assuming the result we will prove later that: sin 2 ⁡ ( x ) = 1 − cos ⁡ ( 2 x ) 2 {\displaystyle \sin ^{2}(x)={\frac {1-\cos(2x)}{2}}} work out an expression for: cos 2 ⁡ ( x ) = {\displaystyle \cos ^{2}(x)=} Be careful with the signs and brackets as you are taking the minus of a minus.
text: Be sure to simplify the formula - your answer should be at least as simple as the formula for sin 2 ⁡ ( x )
