Homework Statement
Evaluate the following in x+iy form.
i3+i
Homework Equations
i=rei\Theta
The Attempt at a Solution
i=rei\frac{pi}{2}
i3+i = i3*ii
(-i)(ei2\frac{pi}{2})
=-ie-\frac{pi}{2}
=-.2079i
I understand how it all works out except \frac{pi}{2}. I can't figure out how...
Homework Statement
A cart is pushed up a ramp with an initial speed v0=2.5m/s. For this problem, you may assume that the cart is frictionless and the acceleration of the cart a=gsin\theta.
A) If the angle of the ramp is \theta=20, what is the maximum distance d that the cart will travel up...
I'm unsure if this should be in homework help or not... but...
In Trig (over a year ago) I remember being taught a equation to find the force being applied (in this case) to the tires of a car when pushing it with "x" force at "y" height.
Lo and behold, I need this equation for a project...
I took a placement test and blew it away. (I tested into calculus, best possible placement for this test.) Everything was rather simple except for this problem which I cannot seem to get right. Can someone show me where I'm going wrong here?
