Sol:因为L[cos2t]=\frac{s}{s^2+4},再將 e^{-st} 加入,则前式的 s 要改成 s-(-1)=s+1 所以 L[e^{-t} cos2t]=\frac{s+1}{(s+1)^2+4} 微分的拉氏变换 设 f(t) 在 t>0 为连续函数,且 f‘(t)、f’‘(t)、f’‘’(t) 存在,则 L[f'(t)]=s F(s)-f(0)⇒ 求...

The correct Answer is:A−1=[cosθ−sinθ−sinθ−cosθ] To find the inverse of the matrix A=(cosθ−sinθ−sinθ−cosθ), we will follow the steps outlined below. Step 1: Calculate the Determinant of AThe determinant of a 2x2 matrix (abcd) is given by ad−bc. For...
Since arcsin is the inverse function of sine, the sine of arcsine of x is equal to x:sin( arcsin x ) = xx has values from -1 to 1:x∈[-1,1]Since sine is periodic, the arcsine of sine of x is equal to x plus 2kπ when k is integer:...
