We can use the sine addition formulas to simplify this. Recall that:sin3x=3sinx−4sin3xThus, we can rewrite sin3x in terms of sinx:sin3x=3sinx−4sin3xSubstituting this into our equation gives:sinx−sin2x+(3sinx−4sin3x)=0This simplifies to:4sinx−sin2x−4sin3x=0 Step...
Using the formulas for sin (A + B), sin (A - B), cos (A + B) and cos (A - B) simplify: sin(x - pi / 3) + cos (x + pi / 3) Write the expression as a single trigonometric expression. \sin (3x) \sin (7x) + \cos (3x) \cos (7x) ...
{eq}\sin(\arccos(x))= \sqrt{1-x^2} {/eq} Answer and Explanation:1 The value of the argument is {eq}2x {/eq}, so we'll replace {eq}x {/eq} with {eq}2x {/eq}. Utilizing the formula {eq}\sin(\arccos(x))=...
Putting it all together, we have: f(−x)=−x5sin2xx4+2x2+1. Step 3: Combine f(x) and f(−x) Now, we can find f(x)+f(−x): f(x)+f(−x)=x5sin2xx4+2x2+1+−x5sin2xx4+2x2+1. This simplifies to: f(x)+f(−x)=x5sin2x−x5sin2xx4+2x2+1=0. Step 4...
