Is there a way to insert points of a coordinate plane onto a Ti-84 plus silver., If SO HOw do you do it?/

I have a TI-84 plus silver edition calculator and i want to know how to insert points so it will show on a graph., is there a way to do that if so how do you do it. Thank you for your help!!-Hit exa

Help with advanced differential problem with an initial condition!

Question asks to solve y = ln(x) / (xy) with initial condition y(1)=2 Thanks!-dy/dx = ln (x) / xy Separate the variables y dy = ln(x)/xdx ∫ y dy = ∫ln(x)/xdx--------(1) ∫ln(x)/xdx =∫ln(x) d[ln

Ten points for a step by step explanation of how to get this problem

Please someone help me explain how to solve for v? m=mo /SQUARE ROOT 1-v^2/c^2.-m/mo=1 /SQUARE ROOT 1-v^2/c^2. mo/m=SQUARE ROOT 1-v^2/c^2. (mo/m)^2 = 1-v^2/c^2. (mo/m)^2 - 1 = -v^2/c^2. 1 - (mo/m)

Log Question..what is log[9](√(9))

what is the answer for log[9](√9)...I think its one but im not sure..I need to find the answer without using a calculator. The base is 9. Thanks-log(base9)(sqrt(9)) = log(base9)(9^0.5) = 0.5log(base9)

The product of three consecutive terms in a geometric sequence is -1000, and their sum is 15. Find the common ratio.-x/r , x , xr=three consecutive terms in a geometric sequence (x/r )(x ) (xr) = -10

Integral Calculus Question

What is the answer to this given equation using u substitution. ∫ (x) / (4x^2 - 5) dx I found this question on the net but suspected the final answer to be wrong.-∫(x)/(4x² - 5) dx u = 4x² - 5 du/8

Maths question: rearrange an equation

Having trouble rearranging this equation and looking for any suggestions on how to solve it. 70941=4c^2 + 14960c + 9310 Just dont know how to find c. c= 37.6-70941 = 4c^2 + 14960c + 9310 0 = 4c^2 + 1

Please help me find the exact value of this expression? tan^-1(-√3/3)

the answer is -pi/6-root three over three is from a special triangle - the 30 60 90.√3/3 is the same as 1/√3.If you draw the special triangle, you can see that 1 and root three are the lengths of the

Please help me verify this identity? (sin x + cos x)²/sin² x - cos² x= sin² x - cos² x/(sin x - cos x)²

(sin x + cos x)²/sin² x - cos² x = (sin x + cos x)(sin x + cos x) / (sin x + cos x)((sin x - cos x) = (sin x + cos x) / (sin x - cos x) now multiply by : (sin x - cos x) / (sin x - cos x) then u ge

How to divide ratios without a calculator

The basic procedure is to write it as a fraction, and then use long division. So express the ratio as .7 ---- 25 and then you need to divide 25 into 7. This is a fairly simple one, because you c

Please help me find all the solutions for this equation? cos²x = -2sin x + 2

the answer is π/2 + 2nπ-cos^2(x) = -2sin(x) + 2 use the fact that sin^2(x) + cos^2(x) = 1 ==> cos^2(x) = 1 - sin^2(x) => 1 - sin^2(x) = -2sin(x) + 2 rearranging gives => sin^2(x) - 2sin(x) + 1 = 0

Suppose that f(x) = x^4 + 7x^2 + 12. Find the values of x such that f(x) = 12

f(x) = 12 => 12 = x^4 + 7x^2 + 12 => x^4 + 7x^2 = 0 =>x^2 ( x^2 + 7 ) = 0 => x = 0 or = +/-sqrt(7) i-f(x) = 12 12 = x^4 + 7x^2 + 12; subtract 12 from both sides 12 - 12 = x^4 + 7x^2 + 12 - 12; si

Compute the first three terms of the Maclaurin series for sqrt(f) if the Maclaurin series for f begins -->

1+ax+bx^2+...-By the given Maclaurin series, f(0) = 1 f (0) = a f (0)/2! = b ==> f (0) = 2b ------------------------ Now, g(x) = [f(x)]^(1/2) ==> g(0) = [f(0)]^(1/2) = 1^(1/2) = 1. g(x) = (1/2) [f(x)
