Product of Sum and Difference is difference of squares of cosines sin = y. cos = x. tan = sin/cos = y/x. It's because by soh cah toa, sin = opposite / hypotenuse, and opposite the central angle is a vertical segment (y axis is also vertical) and the hypotenuse is 1.

Look at this complete trigonometry addition formulas from http Click here👆to get an answer to your question ️ If xsin^3 theta + ycos^3 theta = sinthetacostheta and xsintheta = ycostheta , prove that x^2 + y^2 = 1 . If sin x = 15/17 and cos y = 12/13 , 0 < x < π/2 , 0 < y < π/2, find the values of (i) sin(x + y) (ii) cos(x − y) (iii) tan(x + y). Solution : (i) sin (x + y) Formula for sin (x + y) is sin x cos y + cos x sin y.Now we have to find the values of cos x and sin y. Relazione fondamentale: sin2 x+ cos2 x= 1 jsinxj= p 1 cos2 x, jcosxj= p 1 sin2 x jsinxj= tanx p 1 + tan2 x, jcosxj= 1 p 1 + tan2 x.
