    Could anyone help with the following questions? For number 1, I got -tany=tanx + c but I'm unsure if I could do more with it or to just leave it as so and substitute the value for x nd y

    For number 2, I'm not sure about the simplifying before integration

    Well I think the denominator can be put into a form of y^2*(f(x)). So put the x into the brackets, then bring the numerator and the y^2 to one side and you'll separated all the variables ready for integration.

    For 1 I would just substitute in your x and y now, I cannot see what more you can do.
    Where are you up to with 2?
