I don't know how to make theta so
∅ = theta.
find the slope of the tangent line at
r = sin(6∅) when ∅ = pi/12
tangent line equation
y-y' = m(x-x')
m = dy/dx
The Attempt at a Solution
when ∅ = pi/12 then sin(6∅) = 1
x=rcos(6∅) = 0
y = rsin(6∅) = 1
so If I did the previous parts correctly, then I'm now attempting to find the slope (m).
I do not know how to find it.
m = dy/dx =EITHER= (dy/dr) / (dx/dr) or (dy/d∅) / (dx/d∅). Either way I wouldn't know how to take the derivatives if I did know which one to choose.
Am I doing this correctly? Am I on the right track? Thanks :)
