Yes
f(x)=x+1 g(f(x))=x f(x)-1=x g(x)=x-1
∫ [f'(x)g(x) - f(x)g'(x)]/(f(x)2 + g(x)2) dx = arctan(f(x)/g(x)) + C C is the constant of integration.
g(x) = x + 3 Then f o g (x) = f(g(x)) = f(x + 3) = sqrt[(x+3) + 2] = sqrt(x + 5)
d/dx [f(x) + g(x)] = d/dx [f(x)] + d/dx [g(x)] or f'(x) + g'(x) when x = 3, d/dx [f(x) + g(x)] = f'(3) + g'(3) = 1.1 + 7 = 8.1 d/dx [f(x)*g(x)] = f(x)*d/dx[g(x)] + d/dx[f(x)]*g(x) when x = 3, d/dx [f(x)*g(x)] = f(3)*g'(3) + f'(3)*g(3) = 5*7 + 1.1*(-4) = 35 - 4.4 = 31.1
f(x)= sin(1/x) and g(x)=1/sin(x) [u(v)]' = u'(v) * v', where u and v are functions So f'(x) = sin'(1/x) * (1/x)' = cos(x) * (-1/x2) = -cos(x)/x2 g'(x) = (1/x)' applied to sin(x) * (sin(x))' = -1/(sin2(x)) * cos(x) = -cos(x)/(sin2(x))
x = 75
f = 54
The values of f and g are equal at each point in the domainThe domains of f and g are equal
f and g are inverse functions.
f(x)=x+1 g(f(x))=x f(x)-1=x g(x)=x-1
g(x) = 5. So whatever f(x) or f(-1) is, g of that is going to be 5.
∫ [f'(x)g(x) - f(x)g'(x)]/(f(x)2 + g(x)2) dx = arctan(f(x)/g(x)) + C C is the constant of integration.
∫ [f'(x)g(x) - f(x)g'(x)]/(f(x)2 - g(x)2) dx = (1/2)ln[(f(x) - g(x))/(f(x) + g(x))] + C
C-prime is the dominant note in the song "Defying Gravity" in the musical "Wicked."Specifically, two stanzas are Elphaba's contributions to "Defying Gravity" in "Wicked." The notes of the first stanza are the same as those of the second. The following lists the notes sung by Elphaba in each of her two stanzas on the soundtrack of the original Broadway cast:C-prime, d-prime, f-prime (5 in succession), g-prime;C-prime, d-prime, f-prime (3), g-prime (2);A-prime (2), g-prime, f-prime, e-prime, f-prime, d-double prime (2), c-double prime;C-prime, b flat-prime, a-prime, g-prime, f-prime;C-prime, b flat-prime, a-prime, g-prime, f-prime, e-prime, d-prime;C-prime, b, c-prime, b, c-prime, g-prime, c-prime, c-prime, g;C-prime, b, c-prime, a, g (2);C-prime, b, c-prime, g-prime, c-prime, b, c-prime, c-double prime, b-prime, g-prime, c-prime (2), d-prime (2), c-prime;E-prime (3), d-prime, c-prime, g, c-prime;E-prime (2), d-prime, c-prime, b, g, a-prime, g-prime.
g(x) = x + 3 Then f o g (x) = f(g(x)) = f(x + 3) = sqrt[(x+3) + 2] = sqrt(x + 5)
