Help please!!To solve the problem tan^-1(cos(pi/2)) find the angle in the interval [-pi/2, pi,2] whose tangent equals 0.

Answers

Answer 1

Answer: The cosine of pi/2 is 0 so the problem really says "find the angle between - pi/2 and pi/2 whose tan = 0. That would be the same as asking for the angle whose sin is 0. That would be 0.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer 2

Answer:

Answer:

The angle is 0°.

Step-by-step explanation:

Consider the provided trigonometric function.

$tan^(-1)(cos(\pi)/(2))$

The given interval $[(-\pi)/(2), (\pi)/(2)]$

The value of $cos(\pi)/(2)=0$

Now substitute the respective value in the provided trigonometric function.

$tan^(-1)(tan(0))=0$ by inverse property of trigonometric function

Hence, the angle is 0°.

Answer:

Step-by-step explanation:

Add 29 to both sides of this equation, obtaining: x² - 10x + 25. At this point it becomes obvious that this is a perfect square, the square of x - 5.

Thus, in the first two blanks, write x - 5.

In the second two blanks, write 5 (since 5 is the root corresponding to the factor x - 5).

What are the values of a, b, and c in the quadratic equation –2x^2 + 4x – 3 = 0?a = 2, b = 4, c = 3

a = 2, b = 4, c = –3

a = –2, b = 4, c = 3

a = –2, b = 4, c = – 3

Answers

If you would like to find the values of a, b, and c in the quadratic equation, you can do this using the following steps:

ax^2 + bx + c = 0
-2x^2 + 4x - 3 = 0
a = -2
b = 4
c = -3

The correct result would be a = –2, b = 4, c = – 3.

Final answer:

The values of a, b, and c in the quadratic equation –2x^2 + 4x – 3 = 0 are: a = -2, b = 4, and c = -3.

Explanation:

The values of a, b, and c in the quadratic equation –2x^2 + 4x – 3 = 0 are:

a = -2

b = 4

c = -3

In a quadratic equation in the form ax^2 + bx + c = 0, the coefficients a, b, and c represent different values. In this equation, -2 is the coefficient of the x^2 term, 4 is the coefficient of the x term, and -3 is the constant term.

HELP HELP HURRY!!!!!Which point is located on ray PQ?

A. point M
B. point N
C. point O
D. point R

diagram shown below...

(((<--------M---------N---------O------P--------Q----------R--------S--------->)))

Answers

Answer:

Point R located on ray PQ.

Step-by-step explanation:

Given : Diagram

To find : Which point is located on ray PQ.

Solution : We have given <--------M---------N---------O------P--------Q----------R--------S--------->.

Ray : A part of a line with a start point but no end point (it goes to infinity).

We can see from the diagram ray PQ start from P but it has no end point.

So , point R ans S located on ray PQ but we have option R

Therefore, D. point R located on ray PQ.

If the entire ray is PQ, then all of those points lie on the ray.
