Integration parametric equations:
∫y(θ)x'(θ) dθ
You can then simplify the expression to get the given form
Not sure if this is how you're meant to solve it but it's the way I've learnt

Make sure to use product rule for x=3 theta sin theta

Made that mistake last time

[molten flint]

I can't properly see the rest of the question so I can't help with α&β

[leaden fox]

its the simplification im not sure about

[ionic temple]

Use trig identities

[molten flint]

secx=1/cosx
tanx=sinx/cosx

[ionic temple]

What have you got soo far

[leaden fox]

oh nervermind

i got it
