Answer:
<em>c=6, d=2</em>
Step-by-step explanation:
<em>Equations </em>
We must find the values of c and d that make the below equation be true
Let's cube both sides of the equation:
The left side just simplifies the cubic root with the cube:
On the right side, we'll simplify the cubic root where possible and power what's outside of the root:
Simplifying
Equating the powers of x and y separately we find
c=6
5=3+d
d=2
The values are
Answer:
Tangent at (1,2) has value . And (-2, 4) is the point of intersection of horizontal tangent.
Step-by-step explanation:
Given curve equation,
To find tangent at (x,y)=(1,2) and point of intersection of horizontal tangent, differentiate (1) withrespect to x we get,
At (1, 2), tangent line is,
To find point of intersection of horizontal tangent we have to do,
Thus,
At x=0, y=0
but snce,
at (0,0) there exist a vertical tangent. And,
At x=-2, y=4.
Thus (-2, 4) is the point of intersection of horizontal tangent.
