1. ### gaussian elimination with scaled partial pivoting

Hello can someone help me with this questions: How much time would be used on the computer to solve 2000 equations using gaussian elimination with scaled partial pivoting? give a rough estimate based on operation time thank you
2. ### Area of scaled down triangle

ABC is a triangle with height of 4 cm and base of 7 cm,drawn to a scale of 1cm:3km. Find the actual area of the triangle. How to solve such questions ?
3. ### log scaled values

Hi, I have a chart with a point that looks to be about halfway between 40 and 50, however that axis is log scaled. I'm guessing that it would be about 43. I want to draw a line that represents 45 on that axis, how should I do that? Cheers, T
4. ### Scaled Partial Pivoting

Hi all, I have a problem with the question below: Suppose that 2x_1 + x_2 + 3x_3 = 1 4x_1 + 6x_2 + 8x_3 = 5 6x_1 + ax_2 + 10x_3 = 5 where |a| < 10. For which of the following values of a will there be no row interchange required when solving this system using scaled partial pivoting...
