sin(x) = sqrt(1-cos(x)^2) = tan(x)/sqrt(1+tan(x)^2) = 1/sqrt(1+cot(x)^2) cos(x) = sqrt(1- sin(x)^2) = 1/sqrt(1+tan(x)^2) = cot(x)/sqrt(1+cot(x)^2) tan(x) = sin(x Answers · 2 Two forces of 55N and 85N act on an object simultaneously and the resultant force is 125N. What is the measurement of the angle between the two forces? Proof cos^2(x)=(1+cos2x)/2; Proof Half Angle Formula: sin(x/2) Proof Half Angle Formula: cos(x/2) Proof Half Angle Formula: tan(x/2) Product to Sum Formula 1; Product to Sum Formula 2; Sum to Product Formula 1; Sum to Product Formula 2; Write sin(2x)cos3x as a Sum; Write cos4x-cos6x as a Product; Prove cos^4(x)-sin^4(x)=cos2x; Prove [sinx+sin 2010-02-03 · The proof just depends on Pythagoras' Theorem: draw yourself a 90 degree triangle, label the sides o(opp), a(adj) and h(hyp) relative to angle X then sinX =o/h, cosX=a/h so sin^2X + cos^2X = 1 becomes o^2 + a^2 =h^2 which is you know who's theorem. For real number x, the notations sin x, cos x, etc.
