从步骤 2 可以得出结论,RHS = 2cos x-cos 3 x 等于 LHS,因此, 2cos x-cos 3 x = 2cos x-cos 3 x 左轴= 右轴 因此证明。 示例问题 问题一:求解三角恒等式:4cos 2 x-4cos 4 x+cos 2 2x 解决方案: Taking 2cosx common in the first two terms we get = 2cosx (2cosx-2cos3x) + co...
Here is my take in the general case. I will just give a sketch of a possible proof, which looks feasable even though it has not been completed to the very end (and calculations remain to be checked). Setting: Jn(a,x)=cos(x)(√sin(2x)−a)n Jn(a,x)...
Let F = 2xy i + (x^2 - cos z) j + y sin z k. Find a function so that bigdowntriangle f = F.Given functions are f(x) = x^3 + 2 and g(x) = the cube root of (x 2). Use the composition of functions to determine whether f and g...
