Trigonometry is the most important subject in any engineering aspirant. It cannot be ignored. It needs to be mastered. I have done it and I know how to get a good grasp on solving problems related to trigonometry and I can teach you to become the same.
I love solving problems in geometry. I love solving equations graphically. It's so interactive and interpretative. I have taught basic geometry to many school kids and to college going juniors also.
I love physics a lot. This has been always my favorite subject and I love to solve problems related to it.
