Hint: As we know that the value of Given: We have, Solution: Here in the place of there is . So we convert into . Let’s suppose that Let, in, angle and right angle at B [we will ignore the -ve sign because BC is a length and it can’t be -ve.] So, we required and that is
Hint: As we know that the value of Given: We have Solution: Here in the place of we have . So, we convert to . Let’s suppose that, Let, in , angle and right angle at B. [we will ignore the -ve sign because AC is a length and it can’t be -ve.] [since, ]
Hint: As we know that the value of Given: We have Solution: So here in place of there is . So, we convert into Let’s we suppose that, Let, in , angle and right angle at B. [we will ignore the -ve sign because BC is a length and it can’t be -ve]
Hint: As we know that the value of Given: We have Solution: In place of here is So, we convert into . Let’s suppose that, Let, in , angle and right angle at B. [we will ignore the -ve sign because BC is a length and it can’t be -ve]
Hint: As we know that the value of Given: We have Solution: In place of here is So, we convert into . Let’s suppose that, Let, in , angle and right angle at B.
[we will ignore the -ve sign because BC is a length and it can’t be -ve]
Hint: As we know that the range of Given: Solution: In place of here is So, we convert into . Let’s suppose that, Let, in , angle and right angle at B. [we will ignore the -ve sign because BC is a length and it can’t be -ve]
Hint: As we know that the range of Given: We have Solution: In place of here is So, we convert into . Let’s suppose that, Let, in , angle and right angle at B. [we will ignore the -ve sign because AB is a length and it can’t be -ve]
Hint: We convert in the form of so we know the formula of it. Given: We have to prove that Solution: LHS= Let suppose that and , But we have not . We have only . So, we convert into . Let, in , angle and right angle at B.
Hint: We convert in the form of and we know the formula of it. Given: We have to prove Solution: LHS = Let’s suppose that and . Here, we only have and .So we have to find and . Let, in , angle and right angle at B. Let, in , angle and right angle at B. [we will ignore the -ve sign because PR is a length and it can’t be -ve]
Hint: We convert expression in the form of so we know the formula of it. Given: We have to prove Solution: LHS = …(i) But we have not and . So, we find out first then we put in equation (i) Let, in , angle and right angle at B. [we will ignore the -ve sign because AB is a length and it can’t be -ve]
Let, in , angle and right angle at B. Now, [ put, and ] [ we take LCM of 3 and 12] Hence proved.
Hint: We convert in the form of and we know the formula of it. Given: We have to prove Solution: LHS = Let’s suppose that and …(i) Here we don’t have . So, we find out it and then put all the values in equation (i) Let, in , angle and right angle at B. Let, in , angle and right angle at B. [we will ignore the -ve sign because PQ is a length and it can’t be -ve] Now, Hence proved.
Hint: We know the value of Given: We have to solve to find the value of x. Solution: Here, we have given in place of . So, we convert into Let’s suppose that, We use the identity, [But we can eliminate negative value of , because in RHS of the question only positive value is given.] …(i) Now, .....(ii)
From equation (i) and (ii) we get, Squaring on both sides, Therefore, the answer is .
Hint: As we know that the value of Given: We have to solve to find the value of x. Solution: So, we convert into [] …(i) [ as, is even function, so ] Let’s suppose,
…(ii) …(iii)
Given, … [ from eqn(i) ] …[ using (ii) ] [ ]
Therefore, the answer is
