<p>how do you convert the polar equations and rectangular equations with the 89, can someone tell me how to for example to do the problem that sophia mentioned on the previous page regarding a previous problem on the may test.</p>
<p>yes just use a different email address and login name. it's kind of tricky to find the free practice test link. go to the subject you want to test in and click on US History test center. on the right hand side under control panel it will say your free practice test or whatever.</p>
<p>to do my problem (I'm not sure that was the exact one from May, but it's similar)</p>
<p>on any TI calc, go to mode, switch from function to parametric (or polar for other types of problems), then type in the given equations...look at the graph, and pick the converted equation that matches</p>
<p>y = 3sin(theta) and x= 4cos(theta) will look like an ellipse</p>
<p>mathmatically, you can solve this one by isolating sin(theta) and cos(theta), then using sin^2 + cos^2 = 1 to solve for an ellipse equation</p>
<p>Step 1: Make an account
Step 2: Go to SAT Subject Test Testing Center
Step 3: Click on SAT Subjec Test: Mathematics Level 2
Step 4: Once you are in the "center" you'll notice "Get your first practice test FREE (or something like that)" on bottom of your right hand corner.
Step 5: Click, then choose the exam of your choice.</p>
<p>and that checkout page may have a free test in your shopping cart...if so, "buy" it, then you can go back to the test center to start it...if it says $4.95 it didn'twork....also, search "free practice test" within the website - that worked for me</p>
