Calculators giving wrong answer for sin75

well if you calculate sin75 with a pencil and paper: sin75= sin(45+30) = (sin45 * cos 30) - (sin30 * cos45) which equals 0.2589. but if you plugged the numbers directly into the calculator: sin 75 you

How is zenos paradox incorrect

How is this theory incorrect other than the turtle explanation?-Zenos paradox starts out from the assumption that you can divide space forever. In reality, I think that quantum mechanics tells us it i

If H is a subgroup of G, then by the centralizer C(H) of H we mean the set {x in G | xh = hx all h in H} Prove that C(H) is a subgroup of G.-For h ∈ H we have eh = h = he ⇒ the identity element e ∈ C(

Suppose that x=x(t) and y=y(t) are both functions of t. If y^2+xy−3x=29, and dy/dt=−3 when x=−5 and y=−2, what

Suppose that x=x(t) and y=y(t) are both functions of t. If y^2+xy−3x=29, and dy/dt=−3 when x=−5 and y=−2, what is dx/dt? Not sure how to this question. Thanks!-The given function is y^2+xy−3x=29 di

How to use Newton's method to find where 2 curves intersect

1)the first set of 2 curves is y=x^2 and y=x+2 2) second set of curves is y=e^-x and y=lnx correct to 3 decimal places i just really need to know how to do this as it starts off with finding the gradi

Is this Maths gradient correct

A curve has equation y=xsquared+x Find the gradient of the curve at the point for which x=2 Is the right answer 5-Yep. 2(2) + 1 = 5 indeed.

Math Calculus Derivative Knowledge Question

Q1) When you take the 1st derivative of a function. What does that tell you? Q2) Likewise, when you take the 2nd derivative of the very same function, what does that tell you? Q3) I know usually whe

Show that if a, b, m and n are integers such that m>0, n>0, n|m and a≡b(mod m) then a≡b(mod n)

You are given: (1). n|m (2). a ≡ b (mod m) From (1), there exists some integer x such that m = xn. From (2), there exists some integer y such that (a-b) = ym. Therefore, (a-b) = yxn, and so: There
