(3b.) assuming a and b are not both zero then, solving these equations, one can eliminate both a and b and derive the following formula for va in terms of trigonometric functions (cos, sin, tan, cot, etc.) Vã = tan (6sqrt (lambda) in increasing order, the first four positive eigenvalues from this equation are A = 0.616850275, 1.713472986, 3.358407053, Orient the curve counterclockwise unless otherwise indicated 3.f ff ya da + zº dy, where c is the boundary of the square that is given by 0 < < 51, 0
