 Math Help
Hi, I got this equation (T1^2 + 7T1 - 2) / (8 + 4T1 + T1^2) How do i solve the T1? Can i use 8 + 4T1 + T1^2 = T1^2 + 7T1 -2? Then 8+2 +4T1 -7T1 + T1^2 - T1^2? I tried this, but i cant get the right ans | |

Hi Roff, Thanks! I typed wrongly. The equation should be : tan(kl) = [4 + (2T1)^2 / [2T1^2 + 7T1 - 2] How should i solve? Please advise. Thanks. | |

k is a constant which is 2pi/wavelength and L is the length The answer for T1 = 5.1623 and -1.1623, how do i get these values? Please advise. Thanks. | |

How do you solve it if you don't have values for k and l?
