You get y over 2 is equal to sine of 2t.
And if you divide both sides of this equation by 2,you get y over 2 is equal to sine of t.
Because tangent is equal to sine over cosine.
So now we can use this to substitute back here,so r is equal to sine of theta.
We get y/r is equal to sine of theta, right?
So ln of the absolute value of 1 plus 1 squared is equal to sine of 0 plus c.
So this top graph is y is equal to sine pi x. and then the bottom graph is y is equal to x cubed minus 4x.
You would get y over 2 is equal to sine of t.
And our g of x, this g of x right there for this first case, is the x. g of x is equal to x andf of x is equal to sine of x.
So we know that m over b is equal to sine of theta.
Another example of a non-linear equation is if I wrote y times the second derivative of y with respect to x is equal to sine of x.
Let's say that we have the polar coordinates r is equal to sine of theta plus cosine of theta.
And I'm getting this from mycollege differential equations book. x squared times the second derivative of y with respect to x, plus x times the first derivative of y with respect to x, plus 2y is equal to sine of x.
Cosine of zero is 1. f prime of zero is equal to sine of-- well not minus sine of zero, but what sine of zero?
And if we divide both sides of this equation by B,we get sine of beta over B is equal to sine of alpha over A.
And if we use this trig identity up here, that is equal to sine of a cosine of a plus the sine of a, cosine of a.
So the solution to this differential equation up here is, I don't even have to rewrite it, we figured out c is equal to 1, so we can just scratch this out, and we could put a 1. The natural log of the absolute value of y plus y squared is equal to sine of x plus 1.
We know that-- let me go over here. m over b, right, because this is the hypotenuse, is equal to sine of theta, or that m is equal to b sine of theta, right?
Now if this equation were-- if I rewrote it as x squared d, the second derivative of y with respect to x squared, is equal to sine of x, and let's say I were to square this.
And over here, I'm going to graph still y in the vertical axis, butI'm gonna graph the graph of y is equal to sine of theta, and on the horizontal axis I'm not gonna graph x, but I'm gonna graph theta.
This is equal to 3 sine of pi squared.
You get y is equal to 5 sine of 15 degrees.
This is just sine is equal to opposite over hypotenuse.
So we have 0.735 is equal to the sine of theta 2.
When theta is equal to pi over 2, sine of theta is equal to 1.
So we can say that that is equal to minus sine of b cosine of a.
Π/2 you're going all the way back around like that that gets you all the way back to sine is equal to 1 so sine is equal to 1.
This is equal to 25 sine squared 15 degrees, or sine of 15 degrees squared.
It was x is equal to 3 cosine of 2t and y is equal to 2 sine of 2t.
That's what we just proved, that the sine of minus b, that this is equal to minus sine of b.
