In 542, the 2 is in the ones place. In 324, the 2 is in the tens place.
First, the characteristic solution to the homogeneous part:
has characteristic equation
with roots
. So the characteristic solution has the form
Now for the nonhomogeneous part. Using the method of undetermined coefficients, we can try a particular solution of the form
which has derivatives
Substituting
and its derivatives into the equation gives
which means
so that the particular solution must be
Now the general solution will be
Answer:
Y = - |x-1| - 2
Step-by-step explanation:
Step-by-step explanation: We are given to find the value of x from the following trigonometric equation:
sin55=cosx
We know that the sine of any acute angle is equal to the cosine of its complement and cosine of any acute angle is equal to the sine of its complement.So, from equation (i), we get
sin55 ∘ =cosx
⇒sin55 ∘ =sin(90 ∘−x)
⇒55 ∘ =90 ∘ −x
⇒x=90 ∘ −55 ∘
⇒x=35 ∘
Thus, the required value of x is 35°.
