How do I graph an equation with TI 89?


Just open the Y= equation editor and enter your equation. Use X for T. Make sure the angle unit is in radians.

You do have many math questions. If you expect us to do your homework for you, you should post under an appropriate category. I started this morning answering this question with time-consuming diagrams but did not finish and did not post the answer. During the day I tried to locate your question but for the longest time could not until I launched an all Google search over the Internet and found it. Why should anybody go through all this grief to help you? Well I just did not want my previous work to go to waste.
I hope it helps somebody.

OACB is a parallelogram. R is the resultant.
Use the cosine law in the triangle OAC
R^2=(F_1)^2+(F_2)^2 -2(F_1)(F_2) cos (angle OAC)
Replace the variables by their known values and reduce your equation to cos (angle OAC) =-53/112. Solve for angle OAC in degrees
angle OAC =arccos(-53/112). The angle between the two vectors is the supplementary of angle OAC

I'm trying to do inverse sine and cosine equations but I'm receiving a message that there is a domain error. Is there anything I can do or press like a reset button?


The inverse sine and cosine equations mean "angle who's sine/cosine is:" The bounds of the arguments for these functions must be between 1 and -1, the maximum and minimum values of the sine and cosine functions, because no angle can have a sine or cosine that is greater than 1 or smaller than -1. Also it should be noted that the inverse sine/cosine function is not the same as 1/sine or 1/cosine, although the symbol makes it look like that.

How to input cos x=0.75?


I assume that if you want to input the equation it is with the intent to solve it. If that be the case then what follows will help you input and solve any equation (linear, quadratic, trig, etc.)

Make sure the calculator angle unit is the same as your problem requires (degree, radian, grad). Here are some screen capture to help you. Change the equation to yours. 21c8779.jpg4b6c1ea.jpg
To enter the equation in screen above, use the right arrow.

1. calculation for excel spreadsheet macro for calculating the a right angle triangles hypotinuse and opposite side, angle given


Hello this is Baris,
First off all when you say hypotinuse I think it is a 90 Degree triangle. Total of the angles off a triangle is 180 degree. So it is a simple algebra question.

Hypotinuse is 90
Right angle is R
Left angle is L
Total is 180

Equation is 90+ R +L = 180

We are looking for R, so lets arrange our equation.

R= 180 - 90 - L
R= 90 - L

This is our formula for excel

Lets put it in the excel
Type in A1 "hypotinuse "
Type in A2 "Left Angle"
Type in A3 "Right Angle"

Type in B1 90
Type in B2 "whatever the value given for the left angle"
Type in B3 =90-B2

As soon as you change the value in the cell B2, B3 will change by itself. Hope this helps :)
