Apparently y/TN = dy/dx How is this?
OpenStudy (anonymous):
Let b be the base length of the triangle \[dy/dx=y/b\] \[b=ydx/dy\] \[(yb)/2=tanx\] \[y^2dx/dy=2tanx\] \[dy/dx=y^2cotx/2\] See its simple
OpenStudy (lxelle):
what's b?
OpenStudy (anonymous):
you see the slope of tangent is dy/dx which is equal to tanx which is again equalyto x/TN i have taken TN as b
OpenStudy (lxelle):
is b x?
