Solving Trigonometric Identity EXAMPLE | Pre-Calculus

🤓Tech I use to make and record my lessons:

In this example we solve a common pre-calculus trigonometric identity involving the technique of trigonometric multiplicative inverses. In this case (tanx)(cox)=1.

note: this can be used with other multiplicative identities such as (sinx)(cscx)=1 or (secx)(cosx)=1.

This just helped me finish some problems I was stuck in for the past 2 hours.
No longer thinking about quitting life😂

We can take tanx as 1/cotx and then take lcm easiest way

[ElioMD]

In any cases, how to know by which identity we shall multiply either side. Or, in other words, how to know which identity to use? Thank you

Can you simplify:
1. sint/1-cost + 1-cost/sint
2. sin²∅/cos∅ + cos²∅/cos∅
3. secx sin²x/1 + secx

[AkanyangGaboapolelwe]

What if I multiply by the conjugate of the denominator in either of the sides...and I want to know why we multiply by cotx .??

[Zorro]

I replaced cotx by 1/tanx and then simplify

Easiest question I have seen in my life😂

[steph_koko]

Why didn't the cotx cancel like the cotxtanx

[sadnanjuhib]

I took tan=sin/cos and cot=cos/sin and both sides solves as (cos+sin)/(cos-sin), is this considered a proof?

[garendoesgaming]

is there a website i can use to show all the formulas, like how cos^2 + sin^2 = 1 and the one u used in vid

[sotea]

how'd you know to multiply by cot...??

[Cruzeblade]

Blud just circled and circled and got the answer

[yuvrajkumar]

How do we will get the idea to multiply it by cot x? Like you are goof at maths, but how will a normal student get this idea out of nowhere?

U can still turn to Christ its not too late God bless yall 💯

bro didn't explain why it's equal to 1 lmao
