The given expression is Ctgt(-t)sint + cost(Pi + t).
To simplify, we use trigonometric identities:
Therefore, the expression becomes:
C(-cot(t))(sin(t)) + (-cos(t))
Which simplifies to:
-Ccot(t)sin(t) - cos(t)
So, Ctgt(-t)sint + cost(Pi + t) simplifies to -Ccot(t)sin(t) - cos(t).
The given expression is Ctgt(-t)sint + cost(Pi + t).
To simplify, we use trigonometric identities:
cot(-t) = -cot(t)sin(-t) = -sin(t)cos(Pi + t) = -cos(t)Therefore, the expression becomes:
C(-cot(t))(sin(t)) + (-cos(t))
Which simplifies to:
-Ccot(t)sin(t) - cos(t)
So, Ctgt(-t)sint + cost(Pi + t) simplifies to -Ccot(t)sin(t) - cos(t).
