Symbolic Questions (Part 3) (Homework) MACE JOHN RANDALL MA 141, section 007, Fall 2008 Instructor: Kyle Thompson Web Assign Current Score: 3 out of 3 Due: Saturday, October 4, 2008 10:01 PM EDT Description This assignment will introduce you how to enter basic, advanced, and inverse trig functions. The due date for this assignment is past. Your work can be viewed below, but no changes can be made. 1. 1/1 points Two other common things you might need to enter in symbolic form are log and natural log (ln). The way you enter these is pretty straight forward as long as you remember your parentheses. Some expamples are: log(10x), log(x), ln(10x), and ln(x). Enter the following expression using the proper notation. ((log(10x))/(ln(x)))+x^5 log(10x)/ln(x) + x^5 2. 1/1 points To enter something like sin 2 (x) you need to type: sin(x)^2 or (sin(x))^2. Other examples are: cos(2x)^2, tan(4x+2)^2, and cot(6x)^2. Note: if you try to type the ^2 in the middle (for example, sin^2(x)) WebAssign will not understand your response.

Unformatted text preview: Enter the following expression using the proper notation. cos 2 (9x+6) + sin 2 (10x) cos(9x+6)^2+sin(10x)^2 cos(9x+6)^2 + sin(10x)^2 Symbolic Questions (Part 3) http://www.webassign.net/[email protected]/student.pl?i=200811 ... 1 of 2 11/20/2008 10:14 PM PDF created with pdfFactory Pro trial version www.pdffactory.com 3. 1/1 points Inverse trig functions require you to use the notation below: sin-1 (x) = asin(x) cos-1 (x) = acos(x) tan-1 (x) = atan(x) sec-1 (x) = asec(x) csc-1 (x) = acsc(x) cot-1 (x) = acot(x) Note that asin(x) and sin(x)^(-1) are NOT the same thing. sin(x)^(-1) is equivalent to 1/sin(x). Enter the following expression using the proper notation. sin-1 (4x) + cos-1 (6x) asin(4x)+acos(6x) asin(4x) + acos(6x) Symbolic Questions (Part 3) http://www.webassign.net/[email protected]/student.pl?i=200811 ... 2 of 2 11/20/2008 10:14 PM PDF created with pdfFactory Pro trial version www.pdffactory.com...
