Answer with explanation:
The given function in x and y is,
y= 5 +cot x-2 Cosec x
To find the equation of tangent, we will differentiate the function with respect to x

Slope of tangent at (π/2,3)

Equation of tangent passing through (π/2,3) can be obtained by

⇒There will be no Horizontal tangent from the point (π/2,3).
Answer:
<h2>
50°</h2>
Step-by-step explanation:
AB = AC
So, it is a isosceles triangle.
<B = <C = 65°
Sum of angles of triangle = 180°
< A + < B + <C = 180°
plug the values:
X + 65° + 65° = 180°
Calculate the sum
X + 130° = 180°
Move constant to R.H.S and change its sign
x = 180° - 130°
Calculate the difference
X = 50°
Hope this helps...

We have to find the area a. to the right of 2.120
Answer: We can use excel to find the area to the right of 2.120. The excel function is:
=TDIST(2.120,16,1) = 0.025
Therefore, the area to the right of 2.120 is 0.025
b. to the left of 1.337.
Answer: We can use excel to find the area to the left of 1.337. The excel function is:
=1 - TDIST(1.337,16,1) = 0.900
Therefore, the area to the left of 1.337 is 0.900
