Sometimes it is not possible to solve a trigonometric equation with identities that have a multiple angle, such as sin(2x)sin(2x) or cos(3x)cos(3x). When confronted with these equations, recall that y=sin(2x)y=sin(2x) is a horizontal compression by a factor of 2 of the ...

FDM: Solving Hyperbolic Equations 大黄 Anything about mechanics今天介绍求解双曲型(Hyperbolic)方程。数理方程中,最常见的双曲型方程为二阶波动方程。 (1)∂2u∂t2=c2∂2u∂x2I.C: u(x,0)=f(x), ut(x,0)=g(x) 它只有初始条件,没有边界条件,或者说它的控制域是 (−∞,+∞)。
This function is cos(x) since d/dx cos(x) = sin(x). Therefore, the integral of sin(x) is cos(x) +C. What is the antiderivative of cos(x)? The antiderivative of cos(x) can be found using the Fundamental Theorem of Calculus. We need a function that has the derivative cos(x),...
