Dear University of Cambridge,

I want to know if the following mathematical formulas would be accepted for Alevel Mathematics (9709)

Sin theta= k
Sin theta= (pi)n + (-1)^n *sin^-1(k)

Cos theta= k
Cos theta= 2(pi)n +- cos^-1(k)

Tan theta= k
Tan theta= (pi)n + tan^-1(k)

Where 'n' stands for +\- integers

Yours faithfully,
Suha T.

Dear Suha T.

Thank you for your email and please accept my apologies for the delay in
response.

In response to your email requesting information on Cambridge AS and A
Level Mathematics (9709) through a Freedom of Information request, this
information is accessible from your school and all enquiries of this
nature should therefore be referred there. Your school are best placed to
offer an answer tailored to your particular circumstances and will be able
to provide guidance on all aspects of the examination process including
timetables, support for the examinations, results and certificates.
Private candidates should contact the examinations officer at the centre
at which they sat the exam.

To confirm, we believe that Section 21 of the Freedom of Information Act
2000 applies in this case because the information is accessible by other

this is incorrect please refer the matter back to me and I will look into
it further.

Kind regards
