12.589 we read non−decimal 12 but decimal number 5,8,9 separate read. why? |
x + y + z = 0 2x + 4y − z = 0 3x + 2y + 2z = 0 Solve for x,y,and z |
x + y − z = 0 2x − 3y + z = 0 x −4y + 2z = 0 find the value of x,y, and z |
Solve : x_1 + 2x_2 − 3x_3 = 0 2x_1 + 4x_2 − 2x_3 = 2 3x_1 + 6x_2 − 4x_3 = 3 |
lim_(x→0) (((√(4+x))−(√(4−x)))/x) find the limit above |

Express these both Cartesian and polar form (1) f(z)=3z^2 −2z+(1/z) (2) f(z)=z+(1/z) Thanks |
Express this f(z)=((2z+i)/(z+i)) in polar form where z=re^(iθ) (polar form) |
Express the function f(z)=ze^(iz) into cartesian form and separate it into Real and Imaginary part. M.m |
x^(logx) =100x what is the value of x? |
Express the function f(z)=ze^(iz) in polar form and separate it into Real and Imaginary part. M.m |
As the force on a string increases from 100N to 180N, the string extends by 10cm. The work done in increasing the tension in the string is? |
determine 1)L^− [((4s^2 −17s−24)/(s(s+3)(s−4)))] 2)L^− [((5s^2 −4s−7)/((s−3)(s^2 +4)))] |

Some Important notes 1st Someone has solved a question as wrong, and after he see other people have solved it correctly he delete his poste! hmmm by the way, i have some lapses, i′ve never deleted any. My mistakes keep you from making like them. There is no embarrassment, so please, leave things as they are. 2nd I once composed an question, some people had solved it perfectly, and someone write as comment: “You seem don′t know anything about math” I′ve never replied him, because am not interest in introducing my acadimic qualifications to him. But here i would like to do and say that i exchange the qusetions with others, so if you were a student then try to learn, and if you were a professuer so you can note my questions in your book to show them later to your students in real. The bottom line is let′s exchange a variety of questions! 3rd I noticed some people answer qusetions as a comment! Good! now he seems as the 1st one who solved true! Claps! Can you friend respect who had solved before you? Theses were my three points, for this day. Hope you interest in too, and thanks for you all |
