This solution is known as the general solution. Thus, a solution generalize by means of periodicity is known as the general solution. Note-general soluton is not restricted to only 0 to 2π. The solutions of a trigonometric equation for which 0 <=x < 2pi are called principal solutions.

Krittika Kar 5 years, 9 months ago

For n=1 1(1+1)(1+2)(1+3)=1(2)(3)(4)=24 For P(1) it is true. Let us assumes that it is true for n=k Now, P(k)=k(k+1)(k+2)(k+3)=24x (k+1)(k+2)(k+3)=24x/k.....(1) Now for P(k+1)=(k+1)(k+2)(k+3)(k+4) =24[x(k+4)/k] Therefore, it is true for n=k+1 Thus by PMI, it is true for all n belongs to N

Čůťê Ğīřł ? ? 6 years, 10 months ago

In these type of questions , firstly multiply and divide the term by 2 and then use:: 2 SinA SinB = Cos(A +B ) - Cos ( A-B ) type identities . And then took common terms outside and then again use above identities ... you will get your answer . Its quit tough to solve the whole question over there. thus, I have told you the procedure .. I hope it will help you ...?
