Simplify cos(x)+cos(x)

Problem

cos(x)+cos(x)

Solution

1. Identify the terms in the expression as like terms because they share the same trigonometric function cos(x)

2. Combine the coefficients of the like terms, where each cos(x) has an implicit coefficient of 1

3. Apply the addition 1 + 1 = 2t*o*ƒ*i*n*d(t)*h*e*t*o*t*a*l*n*u*m*b*e*r*o*ƒcos(x)$ terms.

Final Answer

cos(x)+cos(x)=2*cos(x)
