 Hi and welcome to this session. I am Priyanka and let us discuss the solution question with k. Find the values of the trigonometric function. Perfect. And theta is minus 1410. Let us proceed on the bar solution. Perfect. Minus 1410. This can be written as minus perfect 1410 because perfect minus theta is equal to what is minus perfect theta. Now we know that perfect theta repeats itself. We know that perfect theta repeats itself after an interval of two times. So we can write it as perfect 1410 is equal to minus perfect if we multiply t60 by 4 we will get a number which is more than 1410. And if we subtract 30 out of 8 it will become equal to 1410 because t60 multiplied by 4 is 1440. So on subtracting 30 degrees from 1440 degrees we will have 1410 right. Now further it can be written as minus perfect minus 30 degrees because cos 25 is getting multiplied by 4 minus what theta is minus theta itself. Further we know that cos of minus theta is minus cos theta so here we can have minus perfect theta that is 30 degrees minus minus will become a positive. So we have a positive perfect theta. Now the value of perfect theta is equal to 2. So our final answer is 2. That completes the question. I hope you enjoyed the session. Bye for now.
