Can anyone solve the question in this attachement, try to show working where possible so i can see what you have done.
when t=25 degrees , y = 2. Find the equation of the curve.
Integrate both sides:
Plug in t=25 y=2 (Just remember that t is in degrees when you evaluate in your graphing calculator, and not in radians)
Solve for C:
So the curve has equation
To check, differentiate and evaluate.
