Input:
dsolve(y(0.5,x)-2cos(y)*exp(x)=0)
Write:
`dsolve(y(0.5,x)-2cos(y)*exp(x)=0)`
Compute:
$$dsolve(y^{(0.5)}(x) - 2\ cos(y)\ exp(x)=0)$$
Output:
$$dsolve(y^{(0.5)}(x) - 2\ cos(y)\ exp(x)=0)== sec ^{-1} (0.5,2.0\ (C_1+0.886226925452758\ exp(x)))$$
Result: $$sec ^{-1} (0.5,2.0\ (C_1+0.886226925452758\ exp(x)))$$
