What is the reciprocal of z2-r2?
0
How do you Factor z3 - 2z2 9z - 18?
its either (z2+ 9)(z - 2) , (z2+ 2)(z - 9) , or (z2- 9)(z - 2)
The overall force acting on an object after all the forces are combined is the?
After all forces are summed with vector addition, the result is usually known as the net force (Fn) and can be used in the formula (Fn = ma).
Z2 plus 9z plus 18?
z2 + 9z + 18 = z2 + 6z + 3z + 18 = z(z+6) + 3(z+6) = (z+6)*(z+3)
If x equals y-3 and y equals z2 what is x terms of z?
x= z2 - 3
How do you convert Pi-network to T-network?
Any pi network can be transformed to an equivalent T network. This is also known as the Wye-Delta transformation, which is the terminology used in power distribution and electrical engineering. The pi is equivalent to the Delta and the T is equivalent to the Wye (or Star) form. Pi NetworkT Network The impedances of the pi network (Za, Zb, and Zc) can be found from the impedances of the T network with the following equations: Za = ( (Z1*Z2)+(Z1*Z3)+(Z2*Z3) ) / Z2 Zb = ( (Z1*Z2)+(Z1*Z3)+(Z2*Z3) ) / Z1 Zc = ( (Z1*Z2)+(Z1*Z3)+(Z2*Z3) ) / Z3
What are protection zones?
z1,z2,
How do you muiltiply complex numbers?
If z1=a+ib and z2=c+id then the product z1*z2=(ac-bd)+i(ad+bc)
Which is better z2 or s5?
Sony Xperia Z2 lets you display 4K footage on your 4K TV .Galaxy S5 has fingerprint scanner and heart-rate monitor. micro sd card on Z2 up to 16GO, Galaxy S5 up to 128Go Camera Z2 20.7 megapixel, Camera S5 16 megapixels USB port 2.0 on Z2, USB port 3.0 on S5 No Tuner FM (Radio)on S5 and Yes on Z2 Screen IPS with Triluminos on Z2, Super AMOLED on S5 better if you need big storage then Galaxy S5, other depends on how you want to use your phone then decide one or the other
What are the rules for multiplying and adding numbers with exponents?
ax * ay = a(x+y) Example: z2 * z3 = z5 (ax)y = axyExample: (z2)3 = z6 ax/ay = a(x-y) Example: z3/z2 = z1 = z
How do you simplify z plus z?
z2
Given the three numbers z1 z2 z3 show that these complex numbers are vertices of an equilateral triangle inscribed in a circle?
An equilateral triangle is always inscribed in a circle.This means that if you can prove that z1, z2 and z3 are the vertices of an equilateral triangle, they automatically lie on a circle subscribing it.Compute |z1-z2|, |z1-z3| and |z2-z3|. These need to be equal for z1, z2 and z3 to lie on an equilateral triangle. If not, they aren't lying on an equilateral triangle.for z=a+ib, |z| = (a^2+b^2)^(1/2).To find the center c of the circle, note that (z1-c)+(z2-c)+(z3-c) = 0, hence,c = (z1+z2+z3)/3.
