Question about ValuSoft Bible Collection (10281) for PC

Sinx+cosx=5,tanx+secx=3

sinx=?

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..

Square each side

Sin ^2 (x) + cos ^2 (x) +2 sin (x)cos (x) = 49/25

1 + 2sin (x)cos (x) = 1.960

sin (2x) = 0.960

2x = 73.74 deg

x = 36.87 deg

Sin ^2 (x) + cos ^2 (x) +2 sin (x)cos (x) = 49/25

1 + 2sin (x)cos (x) = 1.960

sin (2x) = 0.960

2x = 73.74 deg

x = 36.87 deg

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.

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

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

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

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

=2Sin^2X -1
