Hi,
I want to find the vector which is 20 degrees from the x axis, and 30 degrees from y axis. I tried to do this using dot product of two vectors, but I was unsuccessful.
Can you plz tell me how to do this.
Thanks a lot,
Chamal.
Either I don't understand the question, or it can't be done because 20+30 < 90.
A more typical problem would be to add two vectors, knowing their magnitudes and directions. Go look at your problem again. I'm afraid your statement of it cannot be correct.
You can use trigonometric rules but then you need 3 sides or 2 sides and an inscribed angle. You have 3 angles. You ways you can get the sides from that. I don't realyl know how else to go about that question. I'm sure theres a mistake.
