Free tangent line calculator - find the equation of the tangent line given a point or the intercept step-by-step.
To find the tangent to a curve from an external point, first find the point ‘a’ on the curve where the tangent is. To do this, differentiate the function and set this equal to the change in y over the change in x from the external point to point ‘a’ on the curve.

If a tangent line to the curve y = f (x) makes an angle θ with x-axis in the positive direction, then dy/dx = slope of the tangent = tan = θ.If the slope of the tangent line is zero, then tan θ = 0 and so θ = 0 which means the tangent line is parallel to the x-axis. In this case, the equation of the tangent at the point (x0, y0) is give...If θ →π/2, then tan θ → ∞, which means the tangent line is perpendicular to the x-axis, i.e., parallel to the y-axis. In this case, the equation of the tangent at (x0, y0) is given by x = x0Go through the below tangent and normal problems: Example 1: Find the equation of a tangent to the curve y = (x-7)/[(x-2)(x-3)] at the point where it cuts the x-axis. Solution: As the point cut at the x-axis, then y=0. Hence, the equation of the curve, if y=0, then the value of x is 7. (i.e., x=7). Hence, the curve cuts the x-axis at (7,0) Now, dif...

Free tangent line calculator - step-by-step solutions to help find the equation of the tangent line to a given curve at a given point.
The tangent line to a curve at a given point is a straight line that just "touches" the curve at that point. So if the function is f(x) and if the tangent "touches" its curve at x=c, then the tangent will pass through the point (c,f(c)).
