Dear sage user,
Colud you help me to find z = z(t)?, if:
((2.867e28) / (sqrt (r^3 - (3.535e13)^3 )) ) == (( (2.121e8)(sqrt(2(z^2) -1))) / ( z - sqrt (z^2 - 1)))
where:
r == ((1.97774e13)(sqrt(sqrt(t)))) + ((3.55214e12)(sqrt(t)))
1 < t < 6000
z(t= 1) = 100
r (t= 1) = 3.6e13
thanks!!
I couldn't solve it!!!
