Find the limit:
lim x goes to 0 (x^2/arctan(x))

 =0

Step-by-step explanation:

the x value for which tan(x)=0 is 0

we get an indefinite form, so we use l'hopital's rule

(l'hopitals rule: the limit of an indefinite form is equal to the limit of the derivative of the numerator divided by the derivative of the denominator)

= 0/1 =0

when we graph the function, the graph seems to pass the point (0,0)

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
