2. Use the Pythagorean identity: We know that: sin2x+cos2x=1 Substituting the expressions for sinx and cosx: (msiny)2+(ncosy)2=1 This simplifies to: m2sin2y+n2cos2y=1 3. Express cos2y in terms of sin2y: We can use the identity cos2y=1−sin2y: m2sin2y+n2(1−sin2y)=1 ...
Finally, using the sum-to-product identity, we can simplify it to √2 * sin(x + π/4). 希望这个解答能够帮助到您!如果您有任何疑问或需要进一步的解释,请随时告诉我。
