Solve for x sin(x/2) = square root of (1-cos(x))/2( (sin)(x/2)=√((1-(cos)(x))/2))
Find the derivative of f(x) = -3 x^4 - 2 square root x + 2 / x^2. Find derivative of the function f(x) = (x^4 + 2x) / (square root of x). Given f(x) = 8/Square root of{x}, use the limit definition of the derivative to find f...
By contrast, 0 has only one root — itself. Remember that with the symbol √x, we always denote the non-negative root of x! There is another common way to denote square roots, which expresses the square root in terms of a fractional power: √x = x1/2 = x0.5 The rationale for ...

Since ( 1/2) is constant with respect to ( u), move ( 1/2) out of the integral. ( (arctan)(t)t]_(√x)^(2x)-(1/2(∫ )_(x+1)^(4x^2+1)1/udu)) The integral of ( 1/u) with respect to ( u) is ( (ln)(|u|)). ( (arctan)(t)t]_(√x)^(2x)-1/2(ln)(...
验证f−1(x)=x2+2f-1(x)=x2+2是否为f(x)=√x−2f(x)=x-2的反函数。 点击获取更多步骤... 要验证反函数,请检查f-1(f(x))=x和f(f-1(x))=x是否成立。 计算f-1(f(x))。 f-1(f(x)) 通过将f的值代入f-1来计算f-1(x-2)。
One square root is, from Eq. (3.44), 3eiπ/2=3eiπ/4. The other square root is, from Eq. (3.45), 3eiπ+π/4=3ei5π/4. If a complex number is represented as x+iy, it is easier to transform to polar coordinates before taking the square root of the number....
( x^(1/2)-y^(1/2)=1) Differentiate both sides of the equation. ( d/(dx)(x^(1/2)-y^(1/2))=d/(dx)(1)) Differentiate the left side of the equation. ( -d/(dx)[y]1/(2y^(1/2))+1/(2x^(1/2))) Since ( 1) is constant with respect to ( x), the derivative...
