What is IB, IB* and Na?
Hello
Please could someone rearrange and show the steps for solving simultaneous equations for 2 unknowns, please? The unknowns are r and theta.
Equation 1 is
IB = (2r^2 / (17 x 10^3) x Na) (21 - 11sin^2 theta)
Equation 2 is
IB* = (r^2 / (5 x 10^3) x Na) (21 - 8sin^2 theta)
Thank you very much.
Kind regards,
A
IB = (2r^2 / (17 x 10^3) x Na) (21 - 11sin^2 theta)
Equation 2 is
IB* = (r^2 / (5 x 10^3) x Na) (21 - 8sin^2 theta)
IB/IB* = 2*5*(21 - 11sin^2 theta)/17(21 - 8sin^2 theta)
IB17(21 - 8sin^2 theta) = IB*2*5*(21 - 11sin^2 theta)
Substitute the values of IB and IB* and solve for sinθ and then θ. Using this value of θ, find the value of r.
Do you know how to rearrange for theta? So far I have:
2.841 x 10^-47 x 17 x (21 – 8sin^2θ) = 5.45 x 10^-47 x 2 x 5 x (21 – 11 sin^2θ)
4.8297 x 10^-46 x (21 – 8sin^2θ) = 5.45 x 10^-46 x (21 – 11 sin^2θ)
0.88611 x (21 - (8sin^2) x θ) = 21 - (11sin^2) x θ
