Obtain the solution that satisfies the given conditions of the differential equation, dy/dx = tanxtany , y = pi/4 at x = pi/4
I am looking at this a bit at a time Alan.
Isn't that correct ?
Same thing Melody:
I might have got to the end result quicker if I'd used your formulation though!
Also Melody, it's often advantageous to write the constant of integration as
That allows the result to be written as
$$\ln(\sin y) + \ln(k) = \ln(k \sin y)$$
making later simplification easier.
