Welcome back friends!
In my last post I discussed a powerful mind technique to learn and remember difficult words/ spellings. This technique i.e using mnemonics can further be used even in the field of mathematics. See here:
Calculating trigonometric function
This example is only for those students who need to remember the formulas to calculate sin, cos, tan, which are trigonometric functions.
Tail Owls Are Scared Of Huge Crocodiles And Hippos
Consider the first three words: Tail Owls Are. Here the first letters of each word {T,O,A} in order gives this formula:
Tan = Opposite/Adjacent
Similarly the remaining six words give the following two formulas:
Sin = opposite/hypotenuse
Cos = adjacent/hypotenuse
Also a two other lines can be used for this relationship in trigonometry:

You can easily relate first word of these ratios to trigonometrical ratios e.g.
Sin = P/H, Cosec= H/P, Cos= B/H, Sec=H/B, Tan=P/B, Cot=B/P
Mathematics students are well conversed that P stands here for Prependicular, B for base, and H for hypotenuse of a right angle triangle.
Also sign in various coordinates can also be remembered with a simple sentece;
After School To College.
Here A means All i.e. in the first coordinate all ratios are positive.
S means Sine i.e in the second coordinate Sine and its reciprocal cosecant are positive and rest are negative.
Similar is the case with Tangent and Cosine in third and fourth coordinates.
Remembering the value of “pi”
The value of PI to 5 decimal places is 3.14159. consider the following sentence to remember this value:
How I Wish I Could Calculate.
{3} {1} {4} {1} {4} {9}
Notice that a number is given below each word in the above sentence. This number is the number of letters in that word. For example the first word “How” has 3 letters {H,o,w}.
The second has 1. The third has 4 and so on.
Put all these numbers and you get the value of pi = 3.14159
Remembering the square root of 2 to 10 decimal places
Like the above example, the value of square root of 2 is given by the following sentence.
I have a root of a two whose square is two.
The first word “I” has just 1 letter. The second word “have” has 4 letters and so on. So the value of the square root of two is =1.4142135623
The Number-Rhyme Technique for Remembering up to ten items
To remember up to ten items this technique is usually the best. In this technique, you use a word that rhymes with the numbers from one to ten. It means that the words you use should sound similar to the sound of “1”, “2”, “3”, etc. In the list below, notice that “1”is the bun. These two words end in similar sounds.
1 bun
2 shoe
3 tree
4 door
5 hive {bee hive}
6 sticks
7 heaven
8 gate
9 vine
10 pen
in this technique, you memorize these ten rhyming words. It is relatively easy to remember this list because the chosen words end in sound similar to the sound of words
“1”, “2”, “3”, etc.
you can then use the same list of rhyming words to memorize different lists.
O.K guys, I hope you will benfit a great from this technique. Apply and enjoy success in your exams and day to day life. We will discuss more such techniques later. Bye. Yes do not forget to comment and suggest.
