The first step is to make sure your calculator is in radian mode not degree. Most calculators dont have the cot option to in order to do this on a regular ti-84 calculator we must use the number one. By that i mean cot is the opposite of tan and the tan-1 is not a sign for cot that's a whole nother equation. To set this up in a calculator we divide 1 by the tan of the number given so: `1/tan(1.35)` which will give us .2244557182 this rounded...http://www.enotes.com/homework-help/cot-1-35-use-calculator-evaluate-trigonometric-481977Fri, 31 Jul 2015 16:03:29 PSTWhen we are looking for sin of theta that equals `-sqrt(3)/2 ` we can...

When we are looking for sin of theta that equals `-sqrt(3)/2 ` we can use resources such as the uni circle to help us. The meaning of this equation is at what degree of radian is the y coordinate `-sqrt(3)/2` (sin is y and cos is x). Looking at the picture of the uni circle below we can see that there are 2 values in which the y coordinate is at `-sqrt(3)/2 ` these points are at 240 and 300 degrees. Now the radians are already posted on this...http://www.enotes.com/homework-help/sin-theta-sqrt-3-2-find-two-solutions-each-481995Fri, 31 Jul 2015 15:58:24 PSTThe formula for slope is known as` m = (y2-y1)/(x2 - x1)` In order to...

The formula for slope is known as` m = (y2-y1)/(x2 - x1)` In order to solve this equation we must substitute the variables with the coordination given above x1= -5 x2 = 4 y1 = 0 y2 = 0 plug in: `(0-0)/(4 - (-5)) ----gt 0/ (4+5) -----gt 0/9 -----gt slope = 0`http://www.enotes.com/homework-help/5-0-4-0-find-slope-line-that-passes-through-each-485041Fri, 31 Jul 2015 15:36:26 PSTf(x) = [[|x|]], the the domain and range is given as follows let x=...
