It can be helpful to classify a differential equation, so that we can predict the techniques that might help us to find a functi
Anvisha [2.4K]

Answer:

The equations are not given but the clue to your answer is given below:

Step-by-step explanation:

So the question above talks generally about differential equations (equations whose derivatives can be found) and then describes them thus - the order of a differential equation and the linearity status of a differential equation.

To determine whether or not each of the absent equations is linear, check for the following characteristics of linearity:

1. The maximum number or power that any variable in a linear equation is raised to is 1.

Example: 2x² + 6y = 43y is NOT a linear equation because some or all (in this case, variable x) of the variables in it are raised to a power greater than 1. Variable x is raised to the power of 2.

2. An equation (a linear equation, in this case) contains an 'equal to' sign. This is the reason why it's called an equation. There is a mathematical expression on each side of the equal to sign. Take note of this, just incase one of the options in your question has no equal to sign.

Example: 2x + 6y is NOT a linear equation. It is a linear expression. It contains no equal to sign that compares two distinct mathematical expressions.

3. A linear equation usually has not more than two variables. It is not complex or difficult to solve.

Example: 2x + 6y = 43z is NOT a linear equation.

Cos xcos y=1/2(sin(x+y)+ sin(x-y))
garri49 [273]

Taking Rhs

1/2 [sin(x+y)+ sin (x-y)]

using sinA + sin B = 2 cos (A+B)/2 cos( A - B)/2

1/2 [ 2 Cos ( x+y+x-y)/2 . Cos (x+y-x+y)/2]

=Cos 2x/2. Cos 2y/2 = Cos x . Cos y

Hence true

Every month, the plant grows another 6 cm. After two months
nignag [31]

Answer:

49 cm

Step-by-step explanation:

To find the height of the plant after 4 months, add 12 to 37, since the plant grows 6 cm each month:

37 + 12

= 49

So, after a total of 4 months, the plant will be 49 cm tall
