What would 48/70 scale to?? Given that mid 50s would be in the 90s.. would this be in the 80s?

How many marks was that question 14 q where u had to prove the trig function =0 and then use that cubic equation to prove sin3theta=1/2 (that was the only part of that question I'm confident I got full marks in RIP)

You had sec and cos on the lhs and u had to make sec into 1/cos. From there u create a common denominator of cos and so will have the fraction (1-cos^2x)/cosx... from there u change the 1-cos^2x into sin^2x and that way u will get sinx (sinx/cosx)= sinxtanx which was on the rhs.

I did the exact same calculation in the exam and even now and am getting $191586... could u guys let me know what I'm doing wrong lmao its killing me!!
