Write the equation in spherical coordinates. (a) 4x2 − 3x + 4y2 + 4z2 = 0

1 answer:

6 0

4x^2-3x+4y^2+4z^2=0
here we shall proceed as follows:
x=ρcosθsinφ
y=ρsinθsinφ
z=ρcosφ
thus
4x^2-3x+4y^2+4z^2=
4(ρcosθsinφ)^2-3(ρcosθsinφ)+4(ρsinθsinφ)^2+4(ρcosφ)
but
ρ=1/4cosθsinφ

hence we shall have:
4x^2-3x+4y^2+4z^2
=1/4cosθsinθ(cosθ(4-3sinφ))+4sin^2(φ)

One vertex of a triangle is located at (0,5) on a coordinate grid. After a transformation the vertex is located at (5,0). Which

Grace [21]

Answer:

Two options for this case will be,

Clockwise rotation : -90°

Anti-Clockwise rotation : +270°

Step-by-step explanation:

If we rotate the triangle clockwise -90° then the vertex will be at (5,0).

Similarly by rotatating it anti-clockwise for +270° it will be at same position

Define an action adder :: io () that reads a given number of integers from the key board, one per line, and displays their sum.

The program is an illustration of loops

<h3>What are loops?</h3>

Loops are program statements that are used to perform repetition

<h3>The main program</h3>

The program written in Python, where comments are used to explain each line is as follows:

#This initializes sum to 0

summ = 0

#This gets input for the first number

num = int(input())

#This is repeated while num is not -1

while num!= -1:

#This calculates the sum

summ+=num

#This gets input for the num

num = int(input())

#This prints the sum

print(summ)
