新人求解MATLAB解带变量非线性方程的问题
syms g v a h ; 令f1=v^2/g*cos(a)^2-v^2/g*sin(a)^2+1/(v^2/g^2*sin(a)^2+2*h/g)^(1/2)*v^3*cos(a)^2/g^2*sin(a)-(v^2/g^2*sin(a)^2+2*h/g)^(1/2)*v*sin(a)=0后我用语句 solve(f1,a)得到的解为
atan(1/(2*h*g+2*v^2)^(1/2)*v,1/(2*h*g+2*v^2)*2^(1/2)*((v^2+2*h*g)*(h*g+v^2))^(1/2))
atan(1/(2*h*g+2*v^2)^(1/2)*v,-1/(2*h*g+2*v^2)*2^(1/2)*((v^2+2*h*g)*(h*g+v^2))^(1/2))
atan(-1/(2*h*g+2*v^2)^(1/2)*v,1/(2*h*g+2*v^2)*2^(1/2)*((v^2+2*h*g)*(h*g+v^2))^(1/2))
atan(-1/(2*h*g+2*v^2)^(1/2)*v,-1/(2*h*g+2*v^2)*2^(1/2)*((v^2+2*h*g)*(h*g+v^2))^(1/2))
但正确答案应该是asin(1/(2*h*g+2*v^2)^(1/2)*v)
各位大神们能告诉我哪里出错了吗？我应该怎么做？ 渣渣求解答 {:soso_e179:}
