Find the tangent line to f(x)=cos(x)+sec(x) at x=π The Tangent Line to a Curve: The given function contains trigonometric functions. To find out the tangent line to the given curve, we need to find out the tangent point and the slope m by taking the derivative. ...
Find the line tangent to y=x2−x+7 at x=2. Tangents The point of tangency is the single point at which a straight line just touches a curve. The slope of this straight line, or tangent, is given by the derivative of the function which represents the curve. Knowing the ...

Tangent Line to Circle: The tangent line of a circle is obtained when we know the value of the slope and coordinates of the point(x0,y0)so that we can substitute these values in the general formula of the tangent liney−y0=m(x−x0). For the slope, we'...
Find the tangent line to r=3cos(2θ) when θ=π3. Tangent Line: Polar Coordinates: We find tangent line to a polar curve, by differentiating the polar equation with respect to theta. We use the general formula for the slope of the tangent line to a polar curve. This will...
