Webbexact values of the trigonometric functions at α and β, then it is possible to determine the exact values at α −β, namely sin(α −β)= sinαcosβ −cosαsinβ, cos(α −β)= cosαcosβ +sinαsinβ. A clever geometric proof of these formulae can be found in [12, pp. 46–47], which weshow in Figure 2; proofs with words can be found in any trigonometry textbook. Webb2 apr. 2024 · Trigonometry is a chapter in JEE Main 2024 Mathematics where application of formula is really important. Thus it is important to study the topic in a manner that leads to quick solution of problems. Some of the tips have been given below.
