## Physics: Interesting Follow-up to discussions

For those who participated in the discussions in physics, this article might be interesting to you. We talked extensively about the costs of scientific endeavours and whether the benefit was worth the investment. Soaring costs of raw materials and economic difficulties are bringing this issue to the forefront on many projects.

• One-sided functions
• Continuity
• Derivatives
• Product Rule
• Quotient Rule
• Chain Rule
• Power Rule
• Finding Tangents
• Implicit Differentiation
• Higher Derivatives
• Asymptotes

• Trigonometric Identities
• Trigonometric Proofs
• Derivatives of Trigonometric Functions

**NOTE: The other day I told some of you that sin x approached 1 in a question. I misinterpreted the x as being when x=o but in reflection, x is equal to the angle of rotation thus when there is 0 rotation, sin x is also equal to 0. Please take note of this correction (sin x=0, not 1). Sorry if I confused anyone.
