更多信息对于每分量 N 位 RGB 帧缓冲格式,最低 N 位必须包含蓝色分量,接下来的 N 位必须包含绿色分量,接下来的 N 位必须包含红色分量,其余 32-(3 x N) 位可能包含 alpha。 生成的 32 位值必须以 little-endian 格式存储在内存中。备注 对于Windows Server,此要求是“如果已实现”。
y = (cos^-1 x)^2 হলে [(1-x^2)y2-xy1] -এর মান হবে— 02:53 y = sin(x^2), z = e^(y^2) এবং t = sqrt z হলে dt/dx -এর মান হবে— 02:28 y=a^xb^(2x-1) হলে (d^2y)/dx^2-এর ...
We have to apply the chain rule to evaluate the given condition. Finally we have to compute the differentiated value at the value of (x,y,z). Answer and Explanation: The given function is f(x,y,z)=((sinx)2+(siny)2+(sinz)2). Finding...
