Consider this graph, of sin(x)

http://www.analyzemath.com/trigonometry/graph_sine.gif

You can see that where sin(x) = -1, x = 3/2 Pi (270 degrees). So that is the first of many solutions, which recur every 2 Pi (or 360 degrees) plus or minus from the first solution.

SOURCE: use the identity tan(x/2)=sinx/1+cosx to solve for the value of tan45 degrees

tan(x/2)=sin(x)/(1+cos(x))

Setting x/2=45, means that x=90 (degrees)

But cos(90)=0 and sin(90)=1. Thus tan(45)=1/(1+0)=1.

There are an infinite number of solutions for this. Among them are 0, pi, 2pi, 3pi, and 4pi (see a pattern?).

Nevermind, i assume it's an acronym meaning with respect to x.

so the derivative of (sinx)x is: (cosx)(x) + (sinx)(1)

Simplified: xcosx + sinx

I gues this problem has no solution because both

SinX and cosX should be between -1 and +1 so it's not possible that value of SinX - cosX should be 4

cscx=2 which can also be written as 1/sinx = 2/1

do the recipricol (flip it) and sinx = 1/2 which is pie/6 or 30 degrees.

(sinX-cosX)(sinX+cosX)
=(sin^2 - Cos^2X)

=Sin^2X - (1-Sin^2X)

=Sin^2X -1 + Sin^2X

=2Sin^2X -1

tanx= sinx/cosx,

secx=1/cosx

1+sinx/cosx=3

1+sinx=3cosx---------->1

cosx=5-sinx------------->2

sub 2 in 1

1+sinx=3(5-sinx)

1+sinx=15-3sinx

1+4sinx=15

4sinx=14

sinx=14/4...

this is the solution..
