The calc-alkaline magma series is one of two main subdivisions of the subalkaline magma series, the other subalkaline magma series being the tholeiitic series. A magma series is a series of compositions that describes the evolution of a mafic magma, which is high in magnesium and iron and produces basalt or gabbro, as it fractionally crystallizes to become a felsic magma, which is low in magnesium and iron and produces rhyolite or granite. Calc-alkaline rocks are rich in alkaline earths (magnesia and calcium oxide) and alkali metals and make up a major part of the crust of the continents.
The diverse rock types in the calc-alkaline series include volcanic types such as basalt, andesite, dacite, rhyolite, and also their coarser-grained intrusive equivalents (gabbro, diorite, granodiorite, and granite). They do not include silica-undersaturated, alkalic, or peralkaline rocks.
calc 3 easy question!
I am trying to find the partial derivative of the following function with respect to y. I know how to find it without using the definition...but i want to know how to do it both ways. any help??
g(x,y)=x^2*e^-y
I got: lim as h approaches h...
Hello guys I am not sure if I am doing this right. If you could offer any advice or point out my mistakes I would appreciate it.
Problem: Sketch the graph of the domain of f(x,y,z) = \frac{1}{x^2+y^2-z}
Domain: (x,y,z) \in R^3 \mid x^2+y^2 does not equal z
Graph: I set f(x,y,z) = 1 and...
The question asks:
Which of the points P(3,2,1), Q(2,3,1),R(1,4,1) lie on the plane
3(x-1)+4y-5(z+2)=0?
I know this is a pretty easy problem...but I am drawing a blank on where to start? Should I form vectors from each point ? If so, then what?
A little lost!
Thanks
The question asks to find each sphere that passes through the point (5,1,4) and are tangent to all three coordinate planes.
How would I set that up?
I have no problem finding the equation of a sphere when they give the center point and the radius, of course, but what do I need to know to find...
I am having trouble setting this problem up.
The problem says: Find a vector N that is perpendicular to the plane determined by the points P(0,1,0), Q(-1,1,2), R(2,1,-1), and find the area of triangle PQR.
I know that the cross product of two vectors is perpendicular to the plane of a and b...
Hey all,
I'm a bit stuck on a problem on my online homework for my calc 3 class, hopefully someone can help me out.
Suppose that you push with a horizontal force on a box, to push it up a horizontal ramp, as shown in...
