found this online calculator, gonna use that.

fixed it, I forgot to add the other variations. it would be this below ABC ABc AbC Abc aBC aBc abC abc (on top) * ABC ABc AbC Abc aBC aBc abC abc (on side)

did it wrong. damn it. I found this online calculator, just gonna use that....

when finding the genotype ratio of Aa * Aa we could use binomial expansion (A+a)*(A+a) to get 1:2:1 ratio but how do we find AaBbCc * AaBbCc ?

how do you use chain rule twice to find the derivative of the inverse tan(x^2)?

here is the problem: A particle moves along y=x^3 in the 1st quadrant in such a way that its x-coordinate increase at a steady 12 m/s. How fast is the angle of inclination (theta) at the line joining the particle to the origin when x=2? here is what I currently have dx/dt=12 dy/dt=2x^2 * dx/dt x=2 y=8 I can't find a relation to solve for derivative of theta.

2cos²x-1=2cos(2x) is that an identity or I am missing something, if it is identity then how do you make them equal?

this equation 2sin(x)cos(x) the derivative of that is 2cos(2x) but on my TI-89 it gives me 4(cos(x))^2-2 when plug in an integer, same output answer........ someone show me that they are equal

in the last step, how did you get [math] ( \lim_{h \to 0} \frac{1}{cos(h)+1}) [/math] ? I can see how -sin^2 split into sin(h) and -sin(h).

damn it, I found the problem, I was in degree mode. guess any equation with trig fuction in it has to be graphed on radian mode. thanks

I checked, I entered the equation correctly. Graphed it on my Ti-89 with pretty print on so it was easy to check if I entered correctly. this is puzzling

the question is f(x)=(2x+sin(x))/(2x) as x approaches 0 split the equation and I get f(x)=(2x)/(2x) + sin(x)/(2x) (2x)/(2x)=1? sin(x)/(2x)=(1/2)? (since sin(x)/x=1) add the 2 together and I get the answer 3/2 now this is where the trouble starts, when I graph this function, as x approaches 0 from possible and negative side. the y value is 1.00873 so which answer is correct? the 3/2 from algebra or 1.00873 from graphing? I probally did something wrong somewhere, help me
