Writing unit vectors in terms of sin/cos?

AI Thread Summary
A user sought guidance on expressing unit vectors using sine and cosine but struggled to find resources. They initially searched their textbook and online but felt they might be using incorrect terminology. After some reflection, the user had a realization and figured it out independently. They shared their experience to assist others who might face similar challenges in the future. The discussion highlights the importance of understanding trigonometric principles like Soh Cah Toa for vector representation.

Where could I find a webpage or guide on how to write unit vectors in terms of sin and cos? I looked through my textbook and tried searching google, but I can't find anything...I must be using the wrong terminology.


edit: Delete me! I had one of those epiphany moments and figured it out. :blushing:

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
