thanks defender, I'm beginning to understand. Those are some great links you provided. I forgot about the secant line. That makes more sense to me now.
The square root of x on a graph starts from zero and is infinite. X > zero for the square root of x where x is all real numbers. Square root of x - 4 is x > -4 where x is all real numbers and is infinite.
Try buying the calculus textbooks at the used book store. I got mine for $8.00. It is a $150.00 value. You can learn a lot from the textbooks. You can also go to the libraries. If you are desperate and cannot find a textbook, go to a college and buy it from there. Of course, you would have...
I always use a calculator. I might of missed something in school because I don't remember doing it by hand. I have taken beginners algebra to calculus II and I don't recall doing it by hand. I guess I missed out. Sorry I couldn't help you but I'm asking myself the same question.
You have to start out with basic alegebra and move up to precalculus. You need to know the geometry of physics and basic alegbra will give you equations and formulas for triangles and circles etc. If you want to choose a high physics class like physics for sci and eng then you have to complete...
A tangent to a curve is a line that touches the curve but at what specific point where there is a slope to the curve. Equations like y = X^2 have many slopes because the curve is shaped differently at different points. We can choose 2 points on the graph and find the slope but it will...
How many atoms could fit inside a human cell?
"A person's body is actually made up of trillions of cells (source: Science Concepts - Cells by Silverstein)", but how many atoms could fit inside a human cell?
125 million atoms could fit inside the period at the end of this sentence. But how...
Actually the rate of gravity is a constant. Gravity is always 9.8 m/s regardless but I do apologize! I didn't mean to say s^2 just second no squared since squaring the second makes velocity an acceleration, my mistake.
I used the Distance = Rate * Time equation thus giving me Distance = (9.8m/s^2) * (1 sec) = 9.8 meters
plug in T = 2,3,4 and so fourth and solve for D given R = 9.8 m/s^2
