Hi, I need help with pre-calc - proofing induction An : 1+3+5+...+(2n-1) = n^2 The proof is this: An is true An is true, An +1 is true An is true for all n I really dont understand how to prove t

What would you like to ask?Find integral from 0 to infinity of integral from 0 to infinity of 1 / ((1 + x^2 +

Find integral from 0 to infinity of integral from 0 to infinity of 1 / ((1 + x^2 + y^2)^2) dydx? were learning double integrals and such and Im pretty sure youre supposed to substitute r since youve

Suppose that f is a function of two variables....

Suppose that f is a function of two variables. For small delta x and delta y, we want to find a formula approximating f(x0 +delta x,y0 +delta y) in terms of the value of f and its partial derivatives

Did I write the correct equivalent

Is a+2 equivalent to 2a³-16 _________ 2a²+4a+8 or 2a^3-16/2a^2+4a+8?-2a³-16 _________ 2a²+4a+8 = a³-8 _________ a²+2a+4 = (a-2)(a²+2a+4)_________________a²+2a+4 = a-2-2a³-16 _________ 2a²+4a+8 a

Taylor series for 1/(1+x) about a=3.

Any Help-f(x) =(1+x)^(-1) f(3) = 4^(-1) = 1/4 f(x) = (-1)(1+x)^(-2) = -1/(1+x)^2 f(3) = -1/16 f(x) = (-1)(-2)(1+x)^(-3) = 2/(1+x)^3 f(3) = 2/64 = 1/32 f(x) =2(-3)(1+x)^(-4) = -6/(1+x)^4 f(3) = -6/

How to solve exponential growth

on a particular day 27 cases of the influeza virus were reported to health authorities, 7days later 435 cases were reported. assuming that the growth in the number of cases is exponential, how many c

Write as single radical √(2) * ∛(5)

√(2) * ∛(5)-1) One is square root and the other is cube root; LCM of both is 6. 2) So, √(2) = 2^(1/2) = 2^(3/6) = 6th root of 8 Similarly ∛(5) = 5^(1/3) = 5^(2/6) = 6th root 0f 25 3) Thus taking th

Help with decimals please? 10points

.45 in fraction please explain step by step thanks-.45 = 45/100 = 9/20-basically you see that there are two numbers behind the decimal point, so that means the bottom number (denominator) will be 10

Find the domain of the function

g(x)=6/8-3x-Assuming you mean 6/(8-3x) then the domain is all reals not equal to 8/3.If instead you meant 6/8 - 3x then the domain is all reals-Domain = Real Numbers

Math question about quadratic function

the graph of a quadratic function f intersects the x-axis st x= -2 and x=6. If f(8) = f(p), which could be the value of p?-f(x)= a(x+2)(x-6) so, f(8)= a*10*2 = 20*a and, f(p)=a*(p+2)(p-6)=a*(p^2-4p-1

Pls help me to solve this tricky question really confusing!!!

can u find a number which added to itself one or several times will give a total having the same digits as that number but differently arranged and after the sixth addition will give a total of all ni

Help with this algebra expression thanks pt2

75y + 3 = 8y - 5-67y = -8 y = -8/67-75y + 3 = 8y - 5first subtract 8y from both sides to get ys on one side of the equal sign 67y + 3 = -5Now subtract 3 from both sides to get ys by themselves 67y = -

Please, i need an immediate answer with proof

If an imaginary number i is raised to i, i.e,i^i.., its value is 0.207689...¡i =0.207689... But if a real number or a variable like x is raised to i, how many real numbers, variables exists..? Or, i
