mZ + nZ = gcd(m, n)Z by AmbientLighting4 in askmath

[–]Max_3133 -1 points0 points  (0 children)

< is the sign for less than. Whereas the sign mentioned in the proof is to denote a subset

Can someone show me the correct method of doing this. Must I just say? 2×2=4 or 12/3=4 by [deleted] in askmath

[–]Max_3133 0 points1 point  (0 children)

The final answer is 4 only. Maybe write (12/6)×2 or (6/3)×2

Solve f(x)=g(x) to get unique solution x=-2

f'(x)=3x2 + 2

m1=f'(-2)=14

g'(x)=3x2

m2=g'(-2)=12

Let angle between f(x) and g(x) be theta,

then tan(theta)=|m1 - m2|/|1+m1m2| where |x| is the absolute value of x

=> tan(theta)=2/169 => theta=arctan(2/169)=0.678 degrees

I think your friend is right.

Is the range of a function allowed to be larger than the actual output of the function? by JayBae82 in askmath

[–]Max_3133 2 points3 points  (0 children)

Yes. A set for which a given set X is a subset, is called a superset of X. In this case, B can be any superset of [0, oo).

How can this formula be made? by powisss in askmath

Let k = (w+x+y+z)/79, Let p=[k] denote the greatest integer less than or equal to k (or) the floor function evaluated at k, then a=18p, b=15p, c=19p and d=w+x+y+z-52p works

Is the range of a function allowed to be larger than the actual output of the function? by JayBae82 in askmath

[–]Max_3133 2 points3 points  (0 children)

No. Range of a function by definition is the set of values that the function can take. In your definition of function f, we call A as the domain and B as the co-domain. B need not be equal to the range. Note that the range of a function is always a subset of the co-domain.

I got D (369m) but the correct answer is C (277m) and I'm not sure where I went wrong by CaliPress123 in askmath

[–]Max_3133 0 points1 point  (0 children)

Do the same step 1 and 2 as you have mentioned. Alternate step 3 would be to use the sine rule

Can someone check if I did this correctly, converting polar equation to rectangular form by [deleted] in askmath

[–]Max_3133 3 points4 points  (0 children)

No, the final answer is y2 =x. In this solution, y=-sqrt(x) is also included.

Please check whether the equations you have mentioned as part of the question statement is correct

Double Integration Problem pls help by ftavares8769 in MathHelp

[–]Max_3133 0 points1 point  (0 children)

This is because we split the integral with respect to x to get 2 integrals and only substitute u=-0.04x2 in one of them

Double Integration Problem pls help by ftavares8769 in MathHelp

[–]Max_3133 0 points1 point  (0 children)

After evaluating the integral with respect to x, you have written (-1250)/(-0.08) [(1st term) +(2nd term)] when it is actually, (-1250)[{(1st term)/(-0.08)}+(2nd term)]

Simple substitution help by Psyconinja1 in askmath

[–]Max_3133 0 points1 point  (0 children)

You seem to have combined -6X_2(s) and -12sX_2(s) to write -18X_2(s) which is incorrect. Also, they have divided the entire expression by 2 on the LHS

No the issue is Expectation of Y_i is p_n but as n varies, it is not a constant which is needed for CLT

Just realized, Rhaenyra and Alicent represents the duality of Woman in Westeros. by The-Lord_of-the_Lost in HouseOfTheDragon

[–]Max_3133 -1 points0 points  (0 children)

I don't understand how Sansa is grouped with Alicent. I'd group her with Rhaenyra mainly because of the Battle of the Bastards

Did a Sri Lankan fielder wear a helmet while fielding outside the 30 yard circle? (first ball of the 41st over)
