A Math Question involving trig functions.

Find the values of the six trigonometric functions at each angle: 1.)2π/3 How would i use this angle to find sin, cos, tan, cot, sec, and csc.?-THis angle is in quadrant 2, so sine and csc is positi

WHICH STATISTICAL ANALYSIS TEST DO I USE

hi, sorry about the caps. i did some behavioral tests on 6 crayfish and ranked the tests from 1-5. each crayfish had 4 tests, there was one control. please help me figure out a good test? BQ: How do

How would you round 34.99; please I am confused.

I always get confused on how to round numbers with decimals that include the number 9.-The rule is that you either leave the last digit youre keeping alone, or add 1 to it. So if you were rounding th

Estimate the probability of being injured by a lightning strike in New York

Average death per year 3.6 Average ingeries per year 12.5 populations is 5,689,283-12.5 / 5,689,283 ~ 0.000002197 So the probability of being injured by lightning in a year is approximately 0.0000021

HELP! (It involves graphing equations?)

Im really terrible at doing this, could someone PLEASE EXPLAIN how you got your answer? Thanks :) Graph each system and determine the number of solutions it has. If it has one solution, name it. 1.)

How would I complete the square given: g(x) = x^2 + 12x + 32.. can I use b/2a instead

g (x) = ( x ² + 12x + 36 ) - 36 + 32 g (x) = ( x + 6 ) ² - 4-Thank you for rating---pleased to help.Report Abuse-g(x) = x^2+12x +6^2 - 6^2 + 32 = (x+6)^2 - 4

Can you solve this algebraic sum

Using formula find the value of 8-9a+27a2-27a3, when a= 2 {NOTE THAT THE 2 AFTER SECOND a is square AND THE 3 AFTER THIRD a is cube }-essentially you just replace all of the as with a 2 (also to show

Solving linear systems? algebra 1

solve the linear system. write the answer as an ordered pair. 3x-2y=14 -6x+5y=32 show work for total points (:-multiply the first equation by 2 2(3x-2y=14) -6x+5y=32 solve for y -6x+5y=32 +6x-4y=28 y

Calc help please? hard problem

Find f(x) such that f(x) = sqrt x -1/ sqrt x and f(0) = 13. ALSO if you know how... find the antiderivative (12x^7 + 3x^5/x^4) dx thank you so much!-Problem 1: f(x) = x^(1/2) + x^(-1/2) Integrate

Hard calc problem...any takers

Find the equation of the curve passing through (0, 1/2) if the slope is given by dy/dx = x4 + e2x.-if dy/dx = x^4 + e^(2x), then you just integrate this, and solve the new function using (0, 1/2) to f

Why does this Trigonometry math problem simplify like this

Why does 64 = 36 + 49 - 2(6)(7) cos A simplify to cos A = (36 + 49 -64)/(2(6)(7) How can cos A be isolated like this and please show the steps. thanks-Start 64 = 36 + 49 - 2(6)(7) cos A 0 = -64

Given F(x) = -x^2 + 2x + 8 how would I complete the square

f(x) = - x² + 2x + 8 f(x) = (- x² + 2x) + 8 f(x) = - (x² - 2x) + 8 f(x) = - (x² - 2x + 1) + 8 - (- 1) f(x) = - (x - 1)² + 8 + 1 f(x) = - (x - 1)² + 9 ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯-Start out by grouping the x terms
