Answer:
and
Step-by-step explanation:
The equation of curve is
We need to find the equation of the tangent line to the curve at the point (-3, 1).
Differentiate with respect to x.
The point of tangency is (-3,1). It means the slope of tangent is .
Substitute x=-3 and y=1 in the above equation.
Divide both sides by 130.
If a line passes through a points with slope m, then the point slope form of the line is
The slope of tangent line is and it passes through the point (-3,1). So, the equation of tangent is
Add 1 on both sides.
Therefore, and .
X - y = 2
Rewriting in terms of y,
Subtract x from both sides.
-y = -x + 2
Divide by -1 so that the y is positive.
y = x - 2
Answer:
Step-by-step explanation:
1+sin²(a) +cos²(a) =2
note : for all a in R : sin²(a) +cos²(a) =1
so : 1+sin²(a) +cos²(a) = 1+1 =2
From what I see it seems to be the Distributive Property.
