Texas Instruments TI-15 Explorer Calculator "sin cos" Questions

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

sin, cos, etc. Is there a way to do this....... if you want to square sin(3), press: ( sin 3) )^ 2 1) Selecting the sin/cos/tan key results in sin( or cos( or tan( being displayed on your computer, 2)

sin(x))= cos(x) d^2/dx^2 (sin(x))= d/dx( cos(x))=-sin(x) d^3/dx^3 (sin(x))= -cos(x) d^4/dx^4 (sin(x))=d/dx(-cos(x))=sinx. In 100 successive differentiations you perform the foregoing sequence 100/4=25

...sin(a))/cos(a) ln(sec(a)+tan(a))= ln( (1+sin(a))/cos(a))=X 2*cosh(X)= e^(X)+e^(-X) e^(X)=(1+sin(a))/cos(a) e^(-X)= cos(a)/(1+sin(a)) 2cosh(X)=(1+sin(a))/cos(a) +cos(a)/(1+sin(a))= 2/cos(a) ...

...cos(B) - sin(A)*sin(B) 2. Sin(A+B) = sin(A)*cos(B) + sin(B)*cos(A) Taddahh! Ofcourse, you could just take the sum of A & B and throw that value into cosines input; but then you would be setting ...

...sin(cos(x) dx is cos(cos(x))-sin(x). Use Leibniz's chain rule. d/dx(f(g(x))=d/dg(f(g))*d/dx(g(x)) d/dx(sin(cos(x))=-sin(x)*cos(cos(x)) if x is in radians. If arguments are in degrees, you have a ...

...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 cheated and used a calculator from another ...

sin/cos/tan The sin/cos/tan normally without second key is fine but when the second key (the one above the alpha) key is pressed onto sin/cos/tan should pop up the same but with the negative one power

SIN],[COS],[TAN] followed by the angle value. For inverse trigonometric functions [SIN^-1], COS^-1], or [TAN^-1], Press [SHIFT][SIN], [SHIFT][COS], or [SHIFT][TAN]. For other functions sec(x)=1/cos(x)

...COS, SIN & TAN and are usually require hitting the "2nd F" or "Func" key of the calc to make: SIN button work as COSEC, COS button work as SEC TAN button work as COT Formulas are below: sec x = 1 ...
