Temple of Kraden News: Welcome to the Temple of Kraden! ------ All worshipers may enter the Most Holy Place in single file, reflecting on the bountiful blessing Kraden hath provided unto him or herself since their last visit. Head coverings are not necessary, as true penitence and humility are found within. The Priests and Priestesses of Kraden endeavor to remind all that fresh orange juice is heavily preferred; only whores use frozen.
Greetings, heathen. Perhaps some fortuitous blessing of Kraden's grace hath led you to our humble Temple, or perhaps you are simply curious about this strange and wonderful cult. Should you be willing - and dare to hope - to achieve enlightenment, the door opens before you. Lo! Leave your old life behind! For once you step through, you become something more than just yourself.

You become a Kradenette.

Are you willing to make the rapturous plunge? Do you have what it takes?



One of us! One of us! One of us!

Speaking of proof...
I hate trigonometry identities. Second semester of Pre-Cal is terrible.
1. Simplify: sin^2 x cot^2 x sec x+ sin^2 x

Remember to keep the identities in terms of sine and cosine.

First step: Sin^2 x (cos^2 x/sin ^2 x) (1/cos x) + sin^2 x
Second step: (cancel out similar terms) What you have left is cos x +sin^2 x

2. Simplify: tan x cos x
First step: (sin x/cos x) cos x
Second step: (sin x/ cos x) (cos x/1)
Third step: (cancel similar terms)
Final answer is sin x

3. Proof: cos x+ sin x tan x= sec x

First step: cos x+ [sin x (sin x/cos x)]
Second step: Multiply the trig identities in the bracket.
Cos x+ (sin x^2/cos x)
Third step: cos x/1+ (sin x^2/cos x)
Fourth step: Find common denominator. Multiply numerator and denominator.
(Cos x) Cos x + Sin^2 x = Cos^2 x + sin^2 x
(cos x) 1 cos x cos x cos x

Fifth step: Check the Pythagorean Identities.
Cos^2 x + Sin^2 x = 1
Cos x ( cos x)
Sixth step: Check the reciprocal identities
1/(cos x)= sec x

4. Proof: cos x/(1-sin x) = sec x+ tan x

First step: Rationalize cos x/(1-sin x)
cos x/(1-sin x) (1+sin x)/(1+sin x)
The sign changed because I had to rationalize and reciprocal the denominator.
Second step: Multiply the equation cos x/(1-sin x) (1+sin x)/(1+sin x)
The answer should be [cos x (1+sin x)]/( 1-sin^2 x)
Third step: Use Pythagorean Identities.
The next set up should be: [cos x (1+sin x)]/ (cos^2 x)
Fourth step: Cancel out cos x.
The next set up should be: (1+sin x) /cos x
Fifth step: Split up the denominator and it should look like this:
1/cos x+ sin x/cos x
Sixth step: Use reciprocal identities and quotient identities to verify the right side of the original equation.
1/cos x+ sin x/cos x= secx+ tan x
5. Proof: sec^2 x/ tan x= sec x csc x

First step: sec^2 x become 1/cos^2 x based on the reciprocal identities
The set up of the problem should be (1/cos^2 x) / tan x
Second step: Use quotient identity to change tan x to sin x/ cos x
(1/cos^2 x) / (sin x/ cos x)
Third step: Reciprocal
(1/cos^2 x) (cos x/ sin x)
Fourth step: Cancel out cos x
After canceling it, the problem should be: (1/cos x)(1/sin x)
Fifth step: Check reciprocal identities to prove that (1/cos x)(1/sin x)= sec x csc x

Oh, really? I haven't seen the show, so I didn't know. I'll link it.
