sin3θ = cos2θ find the most general values of θ satisfying the equatios?sinax + cosbx = 0 solve ?Solution) sin (3x)= sin(2x + x)= sin(2x)cos(x) + cos(2x)sin(x)= 2sin(x)cos(x)cos(x) + (1 - 2sin² (x) ) sin(x)= 2sin(x)cos² (x) + sin(x) - 2sin³ (x)= 2sin(x) ( 1 -sin² (x) ) + sin(x) - 2sin³ (x)= 2sin(x) -2sin³ (x) + sin(x) - 2sin³ (x)= -4sin³ (x) + 3sin(x)= 3sin(x) - 4sin³ (x)
Q. Graphs of Sin x and Cos x ? Ans. The sine and cosine functions are related to the path that an object might take around a circle. Suppose a dolphin was swimming over

#questionShow that the system oscillates in simple harmonic motion demonstrated by; , for which the general solution where X = (x – x0)..
If arg (a/b) = pi/2, then find the value of ((a+b)/(a-b)) where a,b are complex numbers. Ans) Arg (a/b) =Pi/2 Tan-1 (a/b)= Pi/2 A/B = tanP/2 ,therefore a/b=infinity.
