Solution by Steps
step 1
Simplify 1+cos(t)1+sec(t)\frac{1 + \cos(t)}{1 + \sec(t)}
step 2
Recall that sec(t)=1cos(t)\sec(t) = \frac{1}{\cos(t)}
step 3
Substitute sec(t)\sec(t) into the expression: 1+cos(t)1+1cos(t)\frac{1 + \cos(t)}{1 + \frac{1}{\cos(t)}}
step 4
Simplify the denominator: 1+1cos(t)=cos(t)+1cos(t)1 + \frac{1}{\cos(t)} = \frac{\cos(t) + 1}{\cos(t)}
step 5
Rewrite the expression: 1+cos(t)cos(t)+1cos(t)\frac{1 + \cos(t)}{\frac{\cos(t) + 1}{\cos(t)}}
step 6
Simplify the fraction: (1+cos(t))cos(t)cos(t)+1\frac{(1 + \cos(t)) \cdot \cos(t)}{\cos(t) + 1}
step 7
Notice that (1+cos(t))(1 + \cos(t)) cancels out: cos(t)\cos(t)
Answer
cos(t)\cos(t)
Key Concept
Trigonometric Simplification
Explanation
The given expression simplifies to cos(t)\cos(t) by substituting sec(t)\sec(t) and simplifying the resulting fraction.
