When will you update the new spec as level maths -edexcel? We have end of year tests coming up

[@pribyvate]

it would be very helpful if you could widen the content on FP3(edexcel) topics such as conic sections, reduction formulae, eigen values, arc length and surface area of revoltution etc.

[@StarbuckCaptain]

Agreed, would be very helpful!

For question 3 you said that the modulus sign is not needed. Would it be incorrect if I wrote the modulus sign in the exam?

How to do for ∫Tanxdx?

[@sarahal5627]

For question1:
It can be In|3x|+C ,right?
For question 6:
It can be (1/sec^2)ln|tanx|+C ,right?

[@ExamSolutions_Maths]

No for both questions. Not sure what you were thinking to arrive at that.
