Questions & Answers for: Casio sin Computers & Internet

cos+tan(sin)=sec This is a trigonometry problem not a calculator's. cos(x) +tan(x).sin(x) = ( cos(x) + (sin(x)/cos(x)).sin(x). After reduction to the same denominator (which is cos(x)) you obtain {cos

If f(x) = sin x, what is the 99th derivative of f(x)? Hello, Frankly my dear, who wants to compute the 99th derivative of sin(x)? d/dx(sin(x))= cos(x) d^2/dx^2 (sin(x))= d/dx( cos(x))=-sin(x) d^3/dx^3

...function keys on my casio fx-300ES Hello, You have 3 keys for the main trigonometric functions: [SIN], [COS] and [TAN] To use them correctly you must set the angle unit to the one your problem ...

...operations are reversed in some places. For example, with most calculators you would type 30 [sin] to calculate the sine function of 30 degrees, with the 115ES its [sin] 30 [=]. The 115ES has ...

how would you do a =14sin85/sin53 Input the following key combination: 14 [*] [sin] 85 [ ) ] [ ÷ ] [sin] 53 [ ) ] [ = ] You should get something that looks like 14*SIN(85)÷SIN(53)

derivatives sin(cosx) The derivative of sin(cos(x)) dx is cos(cos(x))-sin(x). Unfortunately the fx-9850GII doesn't do symbolic differentiation so you'll have to get this result some other way. I ...

find the derivitive of sin(cosx) The 9750GII doesn't have symbolic capabilities so it can't give you a symbolic answer for this. It can evaluate it numerically at any point. The derivative of ...

x=ln(seca+tana) find coshx Sorry I do not like to work with secant and cosecant. sec(a)+tan(a)=(1+sin(a))/cos(a) ln(sec(a)+tan(a))= ln( (1+sin(a))/cos(a))=X 2*cosh(X)= e^(X)+e^(-X) ...

polar rectangular how to convert 40 sin4000T into polar form?? There is nothing to convert, because if T is a real number so is 40sin(4000T). 40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T)) where abs(
