i have solved some questions but my answers don't match with the solution list i have in my book... please if you help me check my answers, i'll be very grateful..
√3 tan x - sec x - 1 = 0 ... i get three solutions to this question but my book's got two... it doesn't mention 5pi/3 + 2n*pi...
can you please correct me with some other questions?? i have solved them but my answers don't match the book's...
√3 tan x - sec x - 1 = 0 ... i get three solutions to this question but my book's got two... it doesn't mention 5pi/3 + 2n*pi... do u think this is also a soln to this question...
solve the trigonometric equations
tan 2(theta) + cot(theta) = 0
When i solved this question, i got pi/2 + 2n*pi and 3*pi/2 + 2n*pi ... but my book says the answer should be pi/6 + n*pi and 5pi/6 + n*pi
Is my answer wrong?? if so, then what's your solution.?
Can you please explain how to factorize x4+2x2+9
If i do it by quadratic formula, i get complex roots ... in my book, it has been factorized to
(x2+2x+3)(x2-2x + 3)
I have practiced solving de moivre's theorem... but i don't know why i keep getting the wrong answer in a particular question although i have checked a hundred times and havn't found a mistake...
this is the question i am talking about:
Simplify the following ( separate into real and imaginary...
thanks for the effort but honestly, i didn't understand your answer... I was asking that it seems more like reflection...in diffraction, the light ray passes through the slit and bends.. but by looking at the diagram I perceived that the x-ray was just bouncing back...
:shy: By looking at the figures showing diffration of x-rays by crystals, it looks more like reflection.. Seems like I am studying reflection... So, where is the diffraction part??
