You have to enter an initial guess on line X=, a default value may be supplied by calculator: It depends on last value stored in X. Once a value is entered press the Fhow to input cos x=0.75? - a5b0f3e.jpgLV

A cone cost 0.90 and sudaes cost 1.65. Tuesday they sold a total of 182 cones and sundaes the receipts for that day was 226.05. How many cones were sold

X = Cones
Y = Sundaes
X + Y = 182 --- Y = 182 - X
0.90 * X +1.65 * y = 226,05
0,90 * X + 1,65 ( 182 - X) = 226,05
0.90 * X + 1,65 * 182 - 1.65 X = 226.05
300.3 - 226,05 = 1,65 x - 0,9 x = 0,75 X
74,25 / 0,75 = X
X = 99
y = 83

Cos (A+B)


You won't need a calculator for this. The cosine of 'a' + 'b' is a semi-important math identity:

1. Cos(A+B) = cos(A)*cos(B) - sin(A)*sin(B)
2. Sin(A+B) = sin(A)*cos(B) + sin(B)*cos(A)


Ofcourse, you could just take the sum of A & B and throw that value into cosines input; but then you would be setting yourself back when it comes time to learn the closely related double-angle identities (which are more important).

Sin, cos, and tan do not seem to work properly.

Press "Mode" Check to see if you are in radian mode or degree mode (one of the top categories)
If you are entering your numbers from sin, cos, and tan as degrees and you are in radians, your answers will be off. Same goes for if you are inputting radians while in degree mode. Hope this helps
