Sometimes I see expressions like tan^2xsec^3x: this will be parsed as `tan^(2*3)(x sec(x))`. Parallel lines always have the same slope, so since y = 2x + 3 has a slope of 2 (since it's in slope-intercept form), the tangent also has a slope of 2. If you want to find the tangent on the point x, you do three things: Insert x into the function, so you got the point where the tangent touches Insert x into the derivation, so you got the slope m of the tangent. See the answer. Evaluate. We can find the tangent line by taking the derivative of the function in the point. A tangent is a line that touches a curve at any point (say in case of a circle it would be a line touching the circumference). Previous question Next question Transcribed Image Text from this Question. To calculate the slope of the total product curve: a) take the change in y divided by the change in x b) find the slope of a line tangent to the TP curve The slope of the line given by the statement is -3, and since it is parallel to the tangent line, the slope of the tangent line is also -3: Now let’s calculate the coordinates of point P.
