yessss, it does ... thanks for that :-)

but tbh, Jedishrfu, I thought it was more like (s-c)* (1+ sc)

Jedishrfu ... yes I got that ... and used the fraction top and bottom to get the RHS denominator right away .. but the top is proving to be a pig .. unless there's something dead easy I'm missing

sorry sammy .. I meant top and bottom multiplied by that because it eliminates stuff and gives the denominator straight away but leaves the numerator slightly more complicated ... It's not homework guys , just a challenge .... and the theory is that we learn a bit plus a bit of experience...

for the LHS i used a multiplier/simplifier of (sinx - cosx)/(sin^2 x) and re-arrangement to achieve the denominator of the RHS P

[mentor note] moved to homework forum hence no template. HI, I'm just having a bit of trouble with the numerator part of this identity ... Resolving the the denominator is fairly straightforward but .. Can anyone shed light on the final couple of steps (sin^3 x - cos^3 x)/(sinx + cosx) =...
