so do i just sub. f1 to find <f|f1> and take integral of f(x) and f1(x) ?

Homework Statement Define the inner product of two polynomials, f(x) and g(x) to be < f | g > = ∫-11 dx f(x) g(x) Let f(x) = 3 - x +4 x2. Determine the inner products, < f | f1 >, < f | f2 > and < f | f3 >, where f1(x) = 1/2 , f2(x) = 3x/2 and f3(x) = 5(1 - 3 x2)/4 Expressed as a...

For an assignment for organic chem the question asks to convert the structure of a compound into a chair conformation my question is that are equatorial substituents always the ones that are represented as a wedge on a structural diagram? If not could someone please give me tips on how to...

Homework Statement The height of a helicopter above the ground is given by h = 2.60t3 , where h is in meters and t is in seconds. After 2.00 s, the helicopter releases a small mailbag. How long after its release does the mailbag reach the ground? Homework Equations yf=y(initial) +...

i was wondering how is taxol targeting specifically at cancerous cells? I mean to say how does it know that a cell is cancerous? Why doesn't it effect skin cells which also have rapid division and stabilizing microtubules in other cells than cancerous would be drastic, wouldn't the immune system...

Thanks for ur reply

i need tips on how to get a mark on the physics exam coming up in 2 weeks. I have trouble connected concepts with problem-solving; for example i know archimedes principle for buoyant force but have trouble solving problems related to finding tension in a suspended mass in water. So any tips on...

nvm dun need help

Homework Statement A rectangular window in a house has dimensions 3.20 m x 2.40 m. As a storm passes by, the air pressure outside drops to 0.948 atm while the pressure inside the house remains 1.00 atm. What is the magnitude of the net force pushing on the window? Take atmospheric pressure...

Homework Statement Three identical train cars, coupled together, are rolling east at 3.97 m/s. A fourth car traveling east at 4.59 m/s catches up with the three and couples to make a four-car train. A moment later, the train cars hit a fifth car that was at rest on the tracks, and it couples...

I seriously dun get this... Is this wrong?: (mass of oliver)* (oliver's velocity)= (mass of rock) (velocity of rock) (59.1)(v)= (0.588) (19.8) v= 0.588*19.8/59.1 v=0.196?

Its seems that since that 19.8 m/s is the velocity oliver will continue with, hence that would be the recoil velocity?:confused: :confused: :confused: But i tried that its not the answer. Ughhh... :cry: I am going to think about this question later since i should really study for my bio...

The Ego The ego begins to develop after birth as infants interact with the world. It develops out of the id;spcialized to help id interact with the world. Ego locates real-world objects that id fanatsizes about, and uses libido id has attached to internal images to power pleasurable...

Would the orginal momentum be zero so would i use 0 as the momentum and find velocity from there? i am so confused:confused: also it says that if oliver throws the rock he would throw it at 19.8 m/s so is that the velocity at the instant he throws it? i seem to be more confused..? :cry:
