Excellent video Prof.

[@justindang6729]

Thank you so much sir. This help a lot

[@soheirmrain975]

hi thank you sir for your video please i have this equation 2*cos(x) - beta*sin(x) + beta*sin(alpha*x) = 0 with alpha and beta two parameters and i need to found x what can i use for solving this equation i first use Matlab with function solve but some one tell me to use inverse Lagrange theorem its look complicate for me ... there is another alternative or something with Matlab to solve my equation?

[@TheShashi02]

sir how we will calculate the nth roots of dispersion relation. the equation is , alpha = (-k_n*tan(k_n)) where n= 1,2,3...... have to find k_n for n=1,2,3...... alpha is constant,

THANK YOU

[@muuubiee]

ok yeah sure... but where are you getting those secondary equations from?

[@phillipmaser132]

Can I use this Newton method or Fsolve to solve mulitvariable quadratics instead linear?

Sir... How to define Constraints in this program

[@elmboom]

i have an error Index exceeds matrix dimensions. Error in F (line 6) k= X(4); Error in Newton (line 9) [f,j]= F(X);
