For cosine functionf(x)=cos(x), the derivative and the integral will be given as: Derivative of cos(x), f′ (x) = −sin (x) Integral of cos(x), ∫f (x) dx = sin(x) + C) [where C is the constant of integration) ...
I'll consider only the integral over the lower triangular regionx+y≤π/2x+y≤π/2where the cosine remains positive, not over the full square0≤x,y≤π/20≤x,y≤π/2, because the OP did not specify what the interpretation of the logarithm is for negative real-valued arguments (princip...
Compute the Fourier cosine transform of a function: In[1]:= Out[1]= Plot the function and its Fourier cosine transform: In[2]:= Out[2]= Fourier cosine transform of reciprocal square root: In[1]:= Out[1]= For a different convention, change the parameters: ...
l(x)=1+2cos(2x)logtan(x)1+tan(x)(1)(1)l(x)=1+2cos(2x)logtan(x)1+tan(x) we have: l(x)+l(π2−x)=1+2cos(2x)logtanx(2)(2)l(x)+l(π2−x)=1+2cos(2x)logtanx hence the original integral equals I=π4+...
There is a part of the spherical surfaceSyou can complete the square: \begin{align} x^2+y^2+z^2-2az+\overbrace{a^2+a^2}^{\text{complete sqr}} &=3a^2 \\ x^2+y^2+(z-a)^2&=4a^2 \end{align} That is ... 共享
