How to get coefficients of triangular functions in an expression

for example, X=k*sin(p1 + x*t) + c*sin(2*p1 + 2*x*t)
when I used 'coeffs' as:
[P, T]=coeffs(X,'sincos')
The result is:
P = k*sin(p1 + x*t) + c*sin(2*p1 + 2*x*t)
T =1
Actually, I want to get the coeffients of X as:
P=[k, c]
T=[sin(p1 + x*t), sin(2*p1 + 2*x*t)]
How can I do to get the desired result?
