      @@HarshithJEE brother, ‘preciate the fact that you’ve done the same but god knows how many of those just understood the concept and how many didn’t, each child is different..some need these kinds of tricks to learn and talking about killing time? Dude this trick can solve questions just like that. You got no authority of saying anything to this teacher who’s come up with such a good way of teaching all kinds of people. I’m sure you must be of the mindset for which only 2-3 good students can just pass out and rest are just left out always, these types of tricks can help save those left out ones. Please reconsider what you said.

      I appeal to the teachers to kindly AVOID this form of teaching... Figuring out ways to memorize is bad especially, when one can teach the same topic intuitively.
      Sin theta defined as opposite side divided by hypotenuse of a right angled triangle.
      Sin 0 -- theta is zero, when opposite side to theta is almost zero. Therefore sin 0 is 0.
      Sin 45 -- theta is 45 when opposite nd adjacent are equal which implies hypotenuse is √2.. Therefore sin 45 is 1/√2
      Sin 90, theta is 90 when opposite and hypotenuse are almost equal. Therefore sin 90 is 1.
      Sin 30, when hypotenuse twice as the opposite side which is evident from the geometry.
      Sin 60, similar to sin 30, hypotenuse is twice as of adjacent. Which means opposite/ hypotenuse is √3/2.
      Guys, please take a look at the geometry and intuitively and logically build these...

If I do a BEd I will be able to teach Management subjects and Data Science which are quite distinct streams. My mum has a BSc BEd & MSc and PhD in Applied Mathematics. She is working on her second PhD at the moment. Noting that she no longer teaches (retired after teaching for 55 years). She is 78 now and still smart as a tack. Also noting that when she started teaching you only needed a BEd to teach (actually I don’t even think one needed a BEd when she started teaching in the late 60/ or early 70s, there used to be an teacher equivalent course).

    Divide by4
    0 1/4 1/2 3/4 1
    Take the square root
    0 1/√2 1/2 √3/2 1
    Then reverse it for cosine function. Then multiply sin function with the multiplicative inverse of cosine function to get the tangent function.
    Similarly by multiplicative inverses of sine cosine & tangent function we get cosecant secant & cotangent functions
    Maybe this can also work . Atleast it worked for me . Maths is a great subject

    I was taught another trick that is also easy...
    just have to take square root of 0, 1/4, 1/2, 3/4, 1....
    Sin 0 sqrt(0) 0. Cos 90
    Sin 30. Sqrt (1/4) 1/2. Cos 60
    Sin 45. Sqrt (1/2) 1/sqrt(2). Cos 45
    Sin 60. Sqrt (3/4). Sqrt(3)/2. Cos 30
    Sin 90. Sqrt(1). 1. Cos 0
    Tan values derived by dividing sin and cos values and we can easily draw the table within seconds..

    Sin 60 =√(3/4)
    Sim 90 =√(4/4)
    Man I think we can do remember this way easier mam once try it mam.
    And ,I am very happy to see a teacher like u who is trying to give thier best to students.but I think this method will help students in memorizing only.
    but the real concept of maths is to understand the subject .
    So , I feel first students should know the derivations (means how these formulas came) and then we can continue with memorizing ( but I also feel that once students are thorough with the derivations then no need of memerozing)
    But , I feel very happy to see a teacher like u ,who is trying to give out thier best.

    There's an easier trick which I used to remember all the ratios.
    Note :- This took me only one minute to remember the ratios when I initially did it.
    Remember only first 5 ratios of sine theta to be able to remember the entire table
    For example,
    Sin0 = 0
    Sin30 = 1/2
    Sin45 = 1/√2
    Sin60 = √3/2
    Sin90 = 1
    Once you remember these five, you can pretty much remember the entire table
    For example,
    Then reverse the order of sine theta to get the cosine ratios
    That is, 1, √3/2, 1√2, 1/2, 0
    Now, we know tanA = sinA/CosA
    So to get tan0° , it must be sin0°/cos0•
    Which is 0/1 = 0
    Similarly, you can get all tangent ratios
    Now you can reciprocate all the ratios
    For example 1/sinA = cosecA
    1/sin45 = cosec45
    Cosec45 = √2
    Similarly, 1/cosA = secA
    1/tanA = cotA
    I hope this trick is helpful for you..

    For imparting the values of Sine, Cos and Tan for angles 30, 45, 60 and 90 so many ways are there yet this is also appreciable as she strains herself very much to drill it in the minds of students...
