Web4 aug. 2024 · Thus sin(3x) = 3sin(x) − 4sin(x)3 In the linearization process on sin(x)n you see that you have products of eikx and e − i ( n − k) x which leads to e ± i ( 2k − n) x. Since 2k − n has the same parity as n, then for n odd, only odd terms can appear. For instance : sin(x)3 = asin(x) + bsin(3x) sin(x)5 = asin(x) + bsin(3x) + csin(5x) WebIf θ=30 o, verify that: sin3θ=3sinθ−4sin 3θ Easy Solution Verified by Toppr Now, LHS=sin3(30 o)=sin90 o=1 Now, RHS=3sinθ−4sin 3θ=3sin30 o−4sin 330 …
