If `f'(x)=g(x) and g'(x)=-f(x)` forall `x and f(3)=5=f'(3)`then `f^((2))(119)+g^((2))(119)=`

If f'(x)=g(x) and g'(x)=-f(x) for all x and f(2)=4=f'(2) then f''(24)+g''(24) is

If f(x)=(x) and g(x)=(5x-2) Find f0g and g0f

f(x) and g(x) are two real valued function.If f'(x)=g(x) and g'(x)=f(x)AA x in R and f(3)=5,f'(3)=4 .Then the value of (f^2(pi)-g^(2)(pi)) is equal to

If f(x)=x^2-3x and g(x)=x+2 find (f+g)(x) , (f-g)(x) and (fg)(x)

Given f'(x)=g(x)" and "g'(x)=f(x)." Also, "f(3)=5" and "f'(3)=4." Then, the value of: "[f(10)]^(2)-[g(10)]^(2)=

If f''(x) =- f(x) and g(x) = f'(x) and F(x)=(f((x)/(2)))^(2)+(g((x)/(2)))^(2) and given that F(5) =5, then F(10) is
