WebbThere is a difference between taking the square root of a number which is always positive (√100=10) and solving x^2=100 which gives both a positive and negative answer. The … Webbthe problem into the sum (or difference) between two sines. We note that sin π/4=cos π/4=1/√2, and re-use cos θ=sin (π/2−θ) to obtain the required formula. Sum The plus option gives: [4.2] We can write cos x as sin (π/2−x), so the left-hand side of Equation 4.2 becomes: =sin (π/2−x)+sin x [4.3] Which is the sum of two sines.
