2016年3月25日 · Cosh is actually just the ordinary Cosine, though it's name is a little fancier: Hyperbolic Cosine. The same goes for the rest of the trigonometric notations. HighSchoolCalculus Mar 25, 2016

2014年6月11日 · Best Answer. We are trying to find an angle whose cosine = 2/3. Using the cosine inverse, we have. arcos(2/3) = about 48.19 degrees

2024年10月31日 · Idek what to do with the problem: Let P(x) be a nonconstant polynomial, where all the coefficients are nonnegative integers. Prove that there exist infinitely many positive integers n such that P(n) is composite.

2015年3月3日 · '2x' is already two things multiplied together: 2*x. Be sure to learn the parts of a polynomial. The number out front is called the coefficient, it's just a constant that is multiplied by the rest of everything else.

2016年8月1日 · Suppose the polynomial p(x)=x^3+ax^2+bc+c has the property that the mean of its zeroes, the product of its zeroes, and the sum of its coefficients are all equal. If the y-intercept of the graph of y=p(x) is 2, what is b? for this answer I will assume it is a typo . The y intercept is the constant so c=2 \(p(x)=x^3+ax^2+bx+c\\ p(x)=x^3+ax^2+bx+2\\\)

Let g(x)=x^4-5x^3+2x^2+7x-11, and let the roots of g(x) be p, q, r, and s. (a) Compute pqr+pqs+prs+qrs. (b) Compute 1/p+1/q+1/r+1/s.
