Reduce the given trigonometric expression to a number:

sin(x)+3tan(x)cot(x)-1/csc(x) -sec^2(x)+tan^2(x)

the 1/csc(x) is a fraction so the 1 is the numerator and csc(x) is the denominator

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?

Can someone me with this? i’m not sure what to put for my equations.
