Question

wyznacz ze wzoru wskazaną zmienna a) U=2k-kr , k b) Z= 5ab2/2 -6(ab-1), a c)t+r/2z=2r/4z+1 , 2

Answer 1

a) U=2k-kr , k

2k=U+ kr / 2

k=1/2 U + 1/2 kr

b) Z= 5ab2/2 -6(ab-1), a

Z= 5ab2/2 -6(ab-1)   / x 2

2z = 10ab4 - 12 ab + 12/ 12b

2Z/12b-10ab4/12b= a

a=2Z/12b-10ab4/12b

c)t+r/2z=2r/4z+1 , 2

t+r/2z=2r/4z+1/  x 4z

t+r razy 4z = 2r+1/ r+1

t+r/ r+1= 2

2=t+r/ r+1
