Simplify error in matlab

I have this code: simplify(((sin*(x^2))*(sec*x))/(1+sec*x))

and getting this error: Error using sin Not enough input arguments.

Error in project1 (line 5) p6=simplify(((sin*(x^2))*(sec*x))/(1+sec*x))

Answer 1

sin*

Is not a valid expression... sin is a function that expects inputs:

sin(1)

What you are doing is

sin*(1)

which will give the same error. Same with sec
